Deploy scalable ring‑fenced Purview operations with Administrative Units
As Microsoft Purview deployments mature, many organisations encounter the same scaling challenge: how do you decentralize operations without fragmenting governance or losing visibility? Administrative Units (AUs) provide a native way to solve this by enabling ring‑fenced operations—allowing teams to operate independently within clearly defined boundaries, while preserving central oversight. This post focuses on the why behind using Administrative Units in Microsoft Purview, with a particular emphasis on scalable, ring‑fenced operations. We’ll walk through three reference architectures that illustrate how Administrative Units support real‑world operating models—without requiring multiple tenants or separate DLP platforms. note: this article and visuals will focus on Administrative Units support in Purview Data Loss Prevention. However, Administrative Units are supported in additional solutions of Microsoft Purview. Refer to Administrative units in Microsoft Purview | Microsoft Learn for more details and support. Why Administrative Units matter for scalable operations Many large organisations operate with decentralized compliance and DLP teams, often aligned to regions, business units, or regulated functions. Historically, this led to one of two sub‑optimal patterns: Multiple, disconnected DLP solutions or tenants Centralized teams managing policies and alerts for parts of the business they don’t own Administrative Units change this model by allowing organisations to: Partition users (and supported resources) into logical units Assign restricted administrators who can only see and act within their unit Apply both global and AU‑scoped policies together, with predictable behavior From a Purview perspective, this enables true business function autonomy, enforced through RBAC and data visibility boundaries, while keeping global services—such as classification—centralized. Reference architecture 1: Layered governance with ring‑fenced operations Scenario An organisation wants to migrate from multiple legacy DLP solutions into Microsoft Purview while preserving independent operations for each business function or region. Architecture highlights This model introduces three distinct layers: Central governance (Global) Global administrators define baseline policies applicable across the tenant Shared services such as classifiers and reusable components remain central Central teams retain cross‑tenant monitoring and reporting capabilities Administrative Units (per business function) Each business function or region is mapped to an Administrative Unit RBAC, policy visibility, and alert management are strictly scoped to the AU Policies created here only affect users within that unit Business function‑level operations Scoped DLP admins manage local policies Alerts and incidents are handled by the owning team Controls can be tuned to meet specific regulatory or operational needs Why this matters This architecture enables a phased migration: Start with a single entity Gradually scale across additional business functions Avoid policy sprawl by consolidating and retiring legacy configurations Crucially, tenant‑wide limits and global services remain unchanged, ensuring consistent performance as scale increases. Reference architecture 2: Ring‑fencing user activity visibility to sub‑business functions Scenario “We have dedicated DLP analysts for executives. DLP alerts and activities for these users must only be visible to that team.” Architecture highlights This model refines the first architecture and allowing to have DLP analysts for a subset of users only. Executive users are placed into a dedicated Administrative Unit representing a subset of users of a business unit. Policies can be published to multiple Administrative Units (ex: Americas + Americas - Execs) In this model: Some DLP administrators may be assigned to multiple AUs so they can publish policies across them Users must belong to a single AU to ensure clean visibility boundaries Why this matters This pattern is particularly effective for: Executive monitoring HR or Legal teams Highly sensitive populations It delivers strict separation of duties without duplicating policies or creating isolated tenants, and aligns with how Purview scopes alerts, activity explorer, and audit data when Administrative Units are used. Reference architecture 3: User activity visibility for multi‑AU users Scenario Some users operate across multiple business functions—for example, executives or shared service leaders—while still requiring controlled visibility for analysts. Architecture highlights User activities are stamped with the sum of all Administrative Units the user belonged to at the time of the activity Scoped DLP administrators: Can only create policies affecting users within their assigned AU. However the sum of their policies will be applicable. Scoped DLP analysts: See all activities for users in their AU, even if those activities were generated by policies scoped to a different AU. Why this matters This model ensures: No loss of investigative context for analysts Predictable visibility when users span multiple organizational boundaries Continued enforcement of AU‑based separation of duties It also reinforces a key principle: Administrative Units control visibility and management scope — not the existence of the underlying activity data. Once a user's in scope of a policy, its related activities/alerts are visible to DLP analysts allowed to review this user's activities. When not to use Administrative Units Administrative Units are a powerful enabler for decentralized, ring‑fenced operations—but they are not required in every Purview deployment. You may choose not to introduce Administrative Units in the following situations: Single, centralized compliance team. If one team owns all policy creation, alert triage, and investigations across the organisation—and there is no requirement to restrict visibility—Administrative Units add limited value. In this model, global role groups already provide sufficient control. No need for visibility or management separation. Administrative Units are primarily about scoping visibility and permissions. If all administrators are expected to see all users, alerts, and activities, AU‑based scoping may introduce unnecessary complexity without operational benefit. Early or small‑scale Purview deployments. Organisations at an early stage of Purview adoption—running a small number of global policies—may find it simpler to start without AUs and introduce them later as operating models mature. Administrative Units do not change tenant limits or global services, so adoption can be phased over time. Requirements driven purely by policy targeting. If the primary requirement is targeting users dynamically for policy application (rather than restricting administrator access or visibility), adaptive scopes alone may be sufficient. Administrative Units become relevant when who can see and manage data is as important as which users are in scope. In short, Administrative Units are best introduced when organisations need to scale operations with clear ownership boundaries, not simply to organise users. Centralized vs. Decentralized Functions in a Ring‑Fenced Operating Model A scalable Microsoft Purview operating model relies on a deliberate split between functions that remain centralized at the tenant level and those that are decentralized to business functions or regions via Administrative Units (AUs). This balance enables autonomy without fragmentation, preserving global consistency while allowing teams to operate independently within defined boundaries. Functions that Remain Centralized Certain capabilities are intentionally retained at the global (tenant) level to ensure consistency, performance, and governance across the organisation. These functions are not delegated to Administrative Units: Global governance and baseline policy definition Central teams define tenant‑wide baseline policies that apply consistently across all users, regardless of AU membership. This ensures minimum protection standards and avoids divergent interpretations of risk. Shared services and reusable components Core services such as classifiers and other reusable components remain centralized to prevent duplication, reduce administrative overhead, and maintain consistent detection behavior across the tenant. Cross‑tenant monitoring and reporting Central teams retain visibility across Administrative Units for monitoring, reporting, and oversight purposes, ensuring that decentralization does not result in blind spots at the organizational level. Tenant‑wide limits and platform behavior Administrative Units do not alter tenant‑wide service limits or global platform characteristics. Keeping these aspects centralized ensures predictable performance and scalability as additional business functions are onboarded. Functions that Are Decentralized via Administrative Units Operational responsibility is decentralized to business functions or regions by mapping them to Administrative Units, with strict scoping enforced through RBAC and data visibility boundaries: Policy creation and management scoped to the AU Business function teams can create and manage policies that only affect users within their Administrative Unit, allowing controls to be tailored to local regulatory or operational requirements without impacting other parts of the organisation. Scoped visibility of alerts, activities, and incidents Administrators and analysts assigned to an AU can only see alerts, activities, and incidents for users in that unit. This enforces separation of duties and prevents unintended access to sensitive data belonging to other functions. Local alert handling and incident response Decentralized teams own the investigation and remediation of alerts generated within their AU, enabling faster response times and clearer accountability. Operational tuning per business function Controls can be adjusted within an AU to reflect specific risk tolerances, regulatory obligations, or operational realities, without creating policy sprawl or requiring separate tenants. Why This Split Matters By clearly separating centralized governance and shared services from decentralized, AU‑scoped operations, organisations can scale Purview deployments in a phased and controlled manner—starting with a single business function and expanding over time—while maintaining consistent governance, visibility, and performance across the tenant. Key takeaways Administrative Units in Microsoft Purview are not just a permissions feature—they are an operating model enabler. Used correctly, they allow organisations to: Scale decentralized operations with confidence Enforce ring‑fenced visibility and management boundaries Combine global consistency with local autonomy For organisations planning large‑scale Purview deployments or consolidating legacy compliance tooling, Administrative Units provide a foundational architecture for sustainable growth.

Microsoft Purview architecture diagrams provide a reference view of how classification, sensitivity labelling, Data Loss Prevention (DLP), Insider Risk Management, and Microsoft 365 Copilot protections work together across Microsoft 365 workloads. They illustrate how organisations can consistently identify, label, and protect sensitive data across endpoints, email, collaboration services, browsers, and AI‑assisted workflows—without prescribing a single deployment model. Classification generates sensitivity signals, labels express organizational protection intent, and DLP enforces that intent in real time across devices, apps, and services. Together, these patterns show how Copilot inherits existing security controls so AI‑generated content remains governed within the same compliance boundaries as organizational data.Data Security Posture Reports
Proving Your Data Security Posture with Confidence Microsoft Purview Posture Reports help organizations prove (not just assume) that their data security controls are working. They provide a clear, outcome‑based view of how effectively sensitivity labels and Data Loss Prevention (DLP) policies are protecting sensitive data across Microsoft 365. Rather than focusing on individual events or alerts, Posture Reports answer a higher‑level question: Are our data protection controls consistently applied and enforced across the organization? We designed Posture Reports to give security, compliance, and business leaders a defensible, measurable view of data security posture, especially critical as organizations adopt Copilot and other AI tools. Purview reporting offers unified data security insights, helping teams identify and address top risks quickly. By consolidating intelligence, it highlights vulnerabilities so you can take prompt action. With contextual information and measurable results, Purview streamlines responses to threats, improves resilience, and supports a proactive security strategy. Microsoft Purview reporting dashboards drive security decisions because they convert massive, fragmented security telemetry into decision‑ready insights: what’s happening, where the risk is, whether controls are effective, and what to do next. For insights on customizing these reports, check out this article. Where can I access these reports? Three Locations: Purview.microsoft.com -> Information Protection -> Reports Purview.microsoft.com -> Data Loss Prevention -> Posture Reports Purview.microsoft.com -> DSPM -> Reports Posture Reports Basics The out-of-box (OOB) reports are built with a combination of Metric and Analytic cards. Note: these reports are refreshed hourly. What is a Metric Card? What is an Analytic Card? Metric cards are designed to highlight a single, high‑level value or KPI and are also the foundation for building custom cards that combine metrics with trend context. Analytics cards provide richer visualizations that help users explore patterns and trends in the data. What they do: A Metric card is used to create a card that pairs a primary metric with its historical trend This allows users to answer not just “What is the value?” but also “Is it improving or declining?” Metric cards are commonly used for adoption, growth, and compliance health indicators These cards focus on showing trends over time What they do: Show distributions, breakdowns, or trends over time Enable comparison across locations, labels, or workloads Support investigation and analysis rather than just reporting These are useful when you need a visual representation rather than a single metric. Display data using charts such as bars, lines, or other visual formats These cards are commonly used for trend analysis, distribution views, and comparative reporting. Both make patterns easier to understand. Report Insights The following table goes into each OOB report and breaks down different viewpoints to help understand how to use them.

DLP Policies Triggered by Workload Total policy trigger volume Unique users involved in triggers Total rules triggered Policy Location (Workload) Endpoint Device Activity Customer Use Cases What are some customer concerns Posture Reports address OOB? Use Case Situation Guidance Labeling & auto-labeling program rollout: “Are we increasing coverage and preventing drift?” Customer situation: A customer is rolling out sensitivity labels and auto-labeling. Leadership asks: “Are we labeling more content?” Security asks: “Are sensitive items still unprotected?” And compliance asks: “Are users downgrading labels?” In posture reports, Information Protection coverage includes label distribution/adoption, auto-labeling posture, and posture drift through label transitions (e.g., label downgrades). This maps directly to “coverage + drift + enforcement” conversations. The built-in IP posture set also calls out label distribution and adoption, auto-labeling policy coverage, and sensitivity label activity as core reports. For “active data” posture, the design intent explicitly includes questions like “What % of my active data estate is labeled vs not labeled?” and “What %/count of unlabeled data has sensitive info?” and “How is labeling protection trending over 30 days?”: perfect for proving program progress (or identifying gaps). DLP tuning & noise reduction: “Which policies/rules are actually firing, and who’s tripping them?” Customer situation: The DLP admin is overwhelmed: policies exist, but they don’t know which ones are actually driving volume (or pain), and which users are repeatedly triggering violations. They need to prioritize tuning based on real-world triggers. Surfaces most triggered DLP rules, most triggered DLP policies, and top users triggering DLP policies. This is directly aligned to the operational question “Are our policies effective?” The service-description blurb explicitly frames DLP posture reports as highlighting most triggered rules, highest-volume policies, and top policy violators. This is exactly what admins use to decide what to tune first. Helps teams move from anecdotal “DLP is noisy” to a ranked view of where to focus (policy/rule/user). CISO Reports, “Are we safer this quarter?” posture readout Customer situation: A CISO (or compliance leader) needs a repeatable, executive-ready snapshot of how the organization is protecting sensitive data, without stitching together audit logs, Activity Explorer screenshots, and spreadsheets. Posture Reports are explicitly positioned as “executive-ready visibility” across Information Protection + DLP. Provides OOB, executive-ready visibility into data protection posture across Information Protection and Data Loss Prevention, so the CISO can answer “Is Purview doing what we intend it to do?” and “Where are the gaps?” quickly. Enables a consistent monthly/quarterly narrative from built-in metrics and trends, with hourly refresh called out as a customer/partner value driver (great for “freshness” credibility in leadership reviews). Uses a rolling window approach; guidance is to save/export what you want to retain for future reference (great for recurring readouts). Frequently Asked Questions (FAQs) Question Guidance What is the least permission required to see Posture Report section for DLP? Information Protection Reader We can see Activity Explorer details inside the reports in a non-simplified view, where all confidential information is visible. If someone has the Security Reader role, will they be able to see these things? Security Reader can see Activity Explorer content surfaced inside Posture Reports, including user/activity-level details that may expose sensitive metadata. If you want a role that can view posture reports but not see confidential item-level signals, Security Reader is not the safe minimum; Information Protection Reader is. Why are our DLP "Device Posture" reports are not in the Posture Reports and only on the DLP Overview page? It will move. Right now, the traffic on home page is high, so we launched there. There will eventually be a deep clone into our "Posture Reports" section, however, it will take some time before it shows up. Can I get reports going back longer than 30 days? We're working on increasing this number but at this time, the reports go back a max of 30 days. Is there any impact on tenant performance when enabling new reporting features? How quickly will reports populate after enabling the feature? No significant impact is expected. If labeling, scanning, and/or DLP policies are already active, reports populate instantly when the feature is enabled (assuming E5 is in place). No additional intrusive operations are performed on the tenant. Can we customize these reports? We have a current public preview in place for posture report customization. Stay tuned for more updates as we continue to build out Microsoft Purview Reporting. Co-Authors: Kevin Kirkpatrick and Jane SwitzerData Security Posture Reports (Custom Workspace and Charts)
For more insights on OOB Reports, check out this article. Overview: NOW IN PUBLIC PREVIEW Microsoft Purview Posture Reports provide a clear, outcome‑based view of how effectively data protection controls, such as Sensitivity Labels and Data Loss Prevention (DLP) policies, are working across Microsoft 365. Rather than focusing on individual alerts or isolated events, Posture Reports help organizations answer a higher‑level, executive‑ready question: Are our data protection controls consistently applied and actually reducing risk at scale? Posture Reports transform complex telemetry from Audit logs, Activity Explorer, and policy enforcement into measurable, defensible insights that security, compliance, and business leaders can act on with confidence. Building on the out‑of‑the‑box experience, Custom Posture Reports enable teams to create scenario‑specific views tailored to their organization’s risk priorities. Key capabilities include: Custom dashboards with drag‑and‑drop sections and cards Built‑in and custom metric or chart cards powered by Activity Explorer data Flexible filtering to support focused investigations and reporting Tips: Start with clear questions, then choose cards that answer them Avoid overcrowding reports; fewer, well‑chosen cards are more effective Use metric cards for status, analytics cards for understanding Treat custom reports as living assets, iterate as needs evolve This allows security teams to move beyond one‑size‑fits‑all reporting and build views aligned to their unique data protection strategy. Preview note: As this feature is in Preview, capabilities, terminology, and UX may change, and not all scenarios are fully documented yet. Key Concepts Where can I access these reports? Three Locations: Purview.microsoft.com -> Information Protection -> Reports Purview.microsoft.com -> Data Loss Prevention -> Posture Reports Purview.microsoft.com -> DSPM -> Reports (CUSTOM COMING) What is a Custom Report? A Custom Report is a user‑created report container where you assemble one or more cards to visualize Information Protection–related data (for example, labeling, classification, or protection activity). Unlike the built‑in reports, custom reports are designed to be adaptable to different audiences and questions. Typical use cases include: Tracking adoption of sensitivity labels over time Monitoring where sensitive data is most concentrated Creating executive‑friendly, KPI‑style summaries Building analyst views for deeper investigation Core Actions in the Custom Reports Experience Add Report creates a new, empty report canvas. This is the starting point where you define: The report name and purpose Create custom reports with your preferred cards and analytics. Add section is used to create a logical grouping within a custom report. A section acts as a container that helps organize cards on the report canvas into meaningful groupings based on purpose, audience, or storyline. What a section does How sections are used Provides structure to a report by grouping related cards together Improves readability and navigation, especially in reports with multiple cards Helps separate different analytical themes within the same report A report can contain one or more sections Each section can include multiple cards (metric cards, chart cards, analytics cards, or custom cards) Sections are added before cards, serving as the layout framework for the report Add Card lets you place a visualization or metric onto the report canvas. Each card answers a specific question, such as “How much data is labeled Confidential?” or “Where is sensitive content growing fastest?” Cards are the building blocks of custom reports and can be mixed and matched within the same report. Permissions: in order to create these reports, you must have permissions to create labels and DLP policies. Built‑in (OOB – Out of the Box) cards: Custom reports include two built‑in card types that can be added to sections: Metric cards – predefined cards used to display key metrics and trends Analytics cards – predefined cards that provide deeper analytical insights Note: In addition to built‑in cards, you can add custom cards (such as metric‑based or chart‑based custom cards) to tailor the report to your scenario. What is a Metric Card? What is an Analytic Card? Metric cards are designed to highlight a single, high‑level value or KPI and are also the foundation for building custom cards that combine metrics with trend context. Analytics cards provide richer visualizations that help users explore patterns and trends in the data. What they do: A Metric card is used to create a card that pairs a primary metric with its historical trend This allows users to answer not just “What is the value?” but also “Is it improving or declining?” Metric cards are commonly used for adoption, growth, and compliance health indicators These cards focus on showing trends over time What they do: Show distributions, breakdowns, or trends over time Enable comparison across locations, labels, or workloads Support investigation and analysis rather than just reporting These are useful when you need a visual representation rather than a single metric. Display data using charts such as bars, lines, or other visual formats Custom cards allow you to define tailored views aligned to your organization’s unique questions. What they do: Focus on specific scenarios not covered by default cards Combine dimensions or filters relevant to your business context Adapt reporting to regulatory, regional, or operational needs When to use them: Organization‑specific KPIs Regulatory or audit‑driven reporting Advanced scenarios that go beyond standard dashboards Custom cards are especially useful for mature programs where built‑in reports are no longer sufficient on their own. Custom Card Configuration The following example illustrates how a metric‑based custom card can be configured to track adoption trends. Scenario: Track adoption of the Confidential sensitivity label over the last 30 days. Card type: Custom card (built from a Metric card) Metric configuration Filters applied What this card shows Metric: Number of items labeled Confidential Time range: Last 30 days (custom) Display format: Compound (shows total count with trend direction) Sensitivity label: Confidential Workload: SharePoint The current total number of items labeled Confidential Whether labeling activity is increasing or decreasing over the last 30 days A focused view of adoption for a specific label and workload This type of custom card is well‑suited for adoption tracking, executive summaries, and ongoing compliance health monitoring. Metric card configuration: Metric cards currently surface up to 7 days of data, providing recent context for the selected metric. Custom surfaces up to the last 30 days of data. You can choose different display formats, such as: Number – a raw count or value Percentage – a proportional view of the metric Compound – a combination of value and trend for quick interpretation You can apply filters to limit the data set to specific criteria (for example, a particular label, location, or workload), allowing the metric to reflect a targeted scenario rather than all data Chart cards are used to visualize data as a graphical chart and can be created as custom cards when you need a visual representation rather than a single metric. Click on Chart Card and under Chart card configuration, select the primary activities: Sensitivity Label Then define the Chart Type Based on the configuration options shown in the UI, the following chart types are available: Vertical bar – compares values across categories using vertical bars; commonly used for side‑by‑side comparisons Horizontal bar – compares values across categories using horizontal bars; useful when category labels are long Pie – shows proportional distribution of values across categories Donut – similar to a pie chart, with a central area that improves readability Line chart – visualizes trends or changes over time Selecting the appropriate chart type helps ensure the custom card clearly communicates the intended insight and improves overall report readability. These cards are commonly used for trend analysis, distribution views, and comparative reporting. Both make patterns easier to understand. Real World Example The business goal this report is addressing is to prove security value and risk reduction, especially to leadership and stakeholders, by tying data protection investments to measurable outcomes. Primary Business Goal: demonstrate that the organization’s data protection controls are effective in reducing financial data risk. The report shows that sensitive financial data is not only being found, but consistently labeled and enforced through DLP, validating that controls are working as intended. Supporting Business Objectives Executive assurance & trust Provide leadership with evidence that compliance and security controls are actively protecting financial data, not just configured. Risk reduction validation Show that financial SITs are being systematically identified and governed, reducing exposure and improper data handling. Value justification for security investments Correlate auto labeling and DLP outcomes to demonstrate ROI on Purview, labeling, and policy investments. Operational confidence Confirm that auto‑labeling policies are accurately detecting sensitive data at scale and triggering appropriate DLP enforcement. Audit and compliance readiness Establish defensible proof that sensitive financial data is discovered, classified, and protected consistently across the environment. Step 1: Create a report, add a name, and description Step 2: Add a section called Key Outcomes (title and description) and add metric cards to show the data at a glance. Step 3: Add another section. Include the following two out of the box charts available. Step 4: Add another section with the out of the box charts Step 5: Add the last section that ties everything together. One out of the box chart and another custom chart. Step 6: for the custom chart above, Do a vertical bar, pivot (the groupings at the bottom of the chart) to Activity. Then, add filters (Sensitive info type: the SITs and Activity: DLPRuleMatch. The report highlights key outcomes, label adoption, application areas, and auto labeling policies. It identifies the main SITs used in labeling and connects them to DLP, demonstrating that the admin's data security measures are effective, particularly with financial information.

C# MIP SDK v1.17.x - AccessViolationException on creation of MIPContext in 64-bit console app
I first logged this on https://stackoverflow.com/questions/79746967/accessviolationexception-when-creating-mipcontext-after-upgrade-to-v1-17 and the responses there have indicated I should raise with Microsoft a a likely bug, but I don't see a clear route to reporting other than here so any response would be appreciated, even if just to direct me to the appropriate reporting location. I've built a simple console app that demonstrates this issue that I'm happy to provide but we're seeing an issue with the 1.17.x version of the C# MIP SDK where an AccessViolationException is being thrown when trying to create an MIP context object. This is for a .Net Framework 4.8 console app built in 64-bit configuration, deployed to a Windows Server 2016 with the latest VC++ redistributable (14.44.35211) installed (both x86 and x64 versions), though we've seen the same on Windows Server 2019 and 2022. When the same app is built in 32-bit and deployed to the same environment the exception doesn't occur. The following code is what I've used to repro the issue: MIP.Initialize(MipComponent.File); var appInfo = new ApplicationInfo { ApplicationId = string.Empty, ApplicationName = string.Empty, ApplicationVersion = string.Empty }; var diagnosticConfiguration = new DiagnosticConfiguration { IsMinimalTelemetryEnabled = true }; var mipConfiguration = new MipConfiguration(appInfo, "mip_data", LogLevel.Info, false, CacheStorageType.InMemory) { DiagnosticOverride = diagnosticConfiguration }; //Expect BadInputException here due to empty properties of appInfo //When built as part of a 64-bit console app this causes AccessViolationException instead MIP.CreateMipContext(mipConfiguration); The AccessViolationException crashes the console app, with the following logged in the Windows Event Log: Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.AccessViolationException at Microsoft.InformationProtection.Internal.SdkWrapperPINVOKE.MipContext_Create__SWIG_1(System.Runtime.InteropServices.HandleRef) at Microsoft.InformationProtection.Internal.MipContext.Create(Microsoft.InformationProtection.Internal.MipConfiguration) at Microsoft.InformationProtection.Utils.MIPHelper.CreateMipContext(Microsoft.InformationProtection.MipConfiguration) The issue doesn't occur with the latest 1.16 version (1.16.149) of the SDK but does appear to be in all versions of the 1.17 release. Library: C# MIP SDK v1.17.x Target App: .Net Framework 4.8 console app Deployed OS: Windows Server 2016, 2019 and 2022 (With .Net Framework 4.8 and latest VC++ redist installed)Secure external attachments with Purview encryption
If you are using Microsoft Purview to secure email attachments, it’s important to understand how Conditional Access (CA) policies and Guest account settings influence the experience for external recipients. Scenario 1: Guest Accounts Enabled ✅ Smooth Experience Each recipient is provisioned with a guest account, allowing them to access the file seamlessly. 📝 Note This can result in a significant increase in guest users, potentially in hundreds or thousands, which may create additional administrative workload and management challenges. Scenario 2: No Guest Accounts 🚫 Limited Access External users can only view attachments via the web interface. Attempts to download then open the files in Office apps typically fail due to repeated credential prompts. 🔍 Why? Conditional Access policies may block access to Microsoft Rights Management Services because it is included under All resources. This typically occurs when access controls such as Multi-Factor Authentication (MFA) or device compliance are enforced, as these require users or guests to authenticate. To have a better experience without enabling guest accounts, consider adjusting your CA policy with one of the below approaches: Recommended Approach Exclude Microsoft Rights Management Services from CA policies targeting All resources. Alternative Approach Exclude Guest or External Users → Other external users from CA policies targeting All users. Things to consider These access blocks won’t appear in sign-in logs— as this type of external users leave no trace. Manual CA policy review is essential. Using What if feature with the following conditions can help to identify which policies need to be modified. These approaches only apply to email attachments. For SharePoint Online hosted files, guest accounts remain the only viable option. Always consult your Identity/Security team before making changes to ensure no unintended impact on other workloads.

TL;DR Java SDK 1.17.154: calling setLabel() then commitAsync() fails with TemplateNotFoundError (TemplateId=2ea3c830-...). Same label/code works on Java 1.16.x and C# 1.17.154. Policy cache cleared, templates/labels verified, token/tenant checked—issue persists. Environment SDK (Java): 1.16.x (OK), 1.17.154 (FAIL) SDK (C#): 1.17.154 (OK) OS (Java): Windows 10/11 (win32 build), Ubuntu 20.04 / 22.04 / 24.04 Java: Corretto/OpenJDK 17.0.16 (x64) Service/Tenant: Microsoft Purview Information Protection Auth: (e.g., user delegated token / app-only token) Code Snippet (Java) // Label apply options LabelingOptions labelingOptions = new LabelingOptions(); labelingOptions.setAssignmentMethod(AssignmentMethod.PRIVILEGED); labelingOptions.setDowngradeJustified(true); labelingOptions.setJustificationMessage("Label Apply"); // Get label Label label = fileEngine.getLabelById(labelId); // Apply label (no explicit template handling) fileHandler.setLabel(label, labelingOptions, new ProtectionSettings()); // Commit File workFile = new File(domainFolder, UidUtil.makeUid()); CompletableFuture<Boolean> commitFuture = fileHandler.commitAsync(workFile.getAbsolutePath()); commitFuture.get(); // <-- Throws TemplateNotFoundError on 1.17.154 Stack trace excerpt: Caused by: com.microsoft.informationprotection.internal.gen.Error: TemplateNotFoundError: Could not find template with id: 2ea3c830-5a0e-4eea-b48b-c72186d453c0, BadInputError.Code=General, CorrelationId=42ffaad4-3a0f-4986-ba9d-b5a79c5fd076 (ProtectionEngine), CorrelationId=16819f70-e419-473f-9895-c756f3dd5e4b (FileHandler) at com.microsoft.informationprotection.internal.gen.SdkWrapperJNI.SwigDirector_FileHandler_Observer_OnCommitFailure(SdkWrapperJNI.java:2688) Expected Behavior setLabel() should apply the label (and its protection) and commit successfully, as it does in Java 1.16 and C# 1.17.154. Actual Behavior commitAsync() fails with TemplateNotFoundError for the GUID referenced by the label’s ApplyProtectionAction. What I’ve Tried Policy/cache refresh: Deleted %LOCALAPPDATA%\Microsoft\MSIP\ / ~/.mip/, reloaded engine. Template/label verification: Confirmed existence and publish scope in Purview portal & via PowerShell/Graph. Label actions check: policyEngine.getLabelActions(labelId) shows an ApplyProtectionAction with that GUID. Token/tenant sanity check: Correct scopes and same tenant. Rollback test: Java 1.16 works; C# 1.17.154 works. Questions Any breaking change in Java 1.17 regarding how protection templates are resolved during setLabel()? Is this a known issue specific to Java SDK 1.17.154 (win32 & Ubuntu 20/22/24 builds)? Should we now explicitly use ProtectionDescriptor / SetProtection() in Java? Can someone review the service logs using the CorrelationIds above? Happy to provide additional logs, PowerShell/Graph queries, or action dumps if needed.

As I was researching on Adobe Acrobat reader and Sensitivity labels, I decided to check if the common alternative PDF readers out there are able to support Purview MIP Sensitivity labels. There is already a published documentation on this for SharePoint-Compatible PDF readers that supports Microsoft IRM: https://learn.microsoft.com/en-us/purview/sp-compatible-pdf-readers-for-irm (last updated Nov-2023) but I wanted to see if these same PDF readers supports the ability for end-users to use/ select labels similar to that of Adobe Acrobat As of 11-June-2025; atleast one of them clearly do: Nitro PDF: Yes. Documentation shows that users can see and use the sensitivity labels. PDF -X.change Editor: Yes. Documentation show that users can see and use the sensitivity labels. (check the official website, I can't hyperlink it because the site is blocked. FOX PDF editor: No. Documentation only states RMS and not clear if it show Purview labels. This is for F.O.X.I.T editor (spelled without the ".") but for some reason there is a community ban on that word and it won't allow me to post the full name PDFescape: No. Sumatra PDF: No Okular: No If there are other PDF readers that I've missed, I encourage you list it down in the comment below. Would love to grow this list.
