Anthropic Claude Purview Data Connector showing all users as Guests..
It appears this connector is not mapping fields properly causing internal users to be mapped as "guests", and since prompts/data isn't maintained for guest users the connector is effectively not gathering anything but noise. Unlike the other data connectors, one cannot create field mappings. Also the app being named using the guid of Microsoft's own "dataassessments" service principal I don't think is intended either. Has anybody else experienced this? See below for an example.Purview DLP Behaviours in Outlook Desktop
We are currently testing Microsoft Purview DLP policies for user awareness, where sensitive information shared externally triggers a policy tip, with override allowed (justification options enabled) and no blocking action configured. We are observing the following behaviours in Outlook Desktop: Inconsistent policy tip display (across Outlook Desktop Windows clients) – For some users, the policy tip renders correctly, while for others it appears with duplicated/stacked lines of text. This is occurring across users with similar configurations. Override without justification – Users are able to click “Send Anyway/Confirm and send” without selecting any justification option (e.g. business justification, manager approval, etc.), which bypasses the intended control. New Outlook: Classic Outlook: This has been observed on Outlook Desktop (Microsoft 365 Apps), including: Version 2602 (Build 19725.20170 Click-to-Run) Version 2602 (Build 16.0.19725.20126 MSO) Has anyone experienced similar behaviour with DLP policy tips or override enforcement in Outlook Desktop? Keen to understand if this is a known issue or if there are any recommended fixes or workarounds.
I just want to secure AI. DLP vs Info Protection vs DSPM vs Governance vs...
I'm with an MSP, and I've avoided Purview like the plague, because it seems to be suffering from the same 'made by marketing teams' 'strategy' the 365 documentation is. However, it's my understanding Purview policies are needed for Data control of Copilot. Here's my issue: all of these different 'solutions' sound like the exact same thing, but are pitched as if they are something different. i'm going to post a couple of descriptions for these 'solutions' to illustrate this. 'discover, label, and protect sensitive and business-critical info' 'make sure your organization can identify, monitor, and protect sensitive info across the expanding Microsoft 365 landscape' 'discover and secure all your sensitive data across Microsoft 365 and non-365 data sources' 'Discover, label, and protect sensitive and business-critical info across your multicloud data estate.' I genuinely do not have time to figure out what each of these 'solutions' are, then figure out their policies, then their giant library of settings (below)... It's not even clear to me what's active NOW, considering we never licensed Purview - but somehow have been roped into it. It SEEMS like these are all variations of marketing terms, which all point to 3-4 actual technical implementations in obscure ways. Can someone advise on the ACTUAL technical policies we want to target and enable? Or just give some clarity? I've never felt so overwhelmed or disconnected from Microsoft's environment. We just want to secure our tenant's AI usage.Purview Data Map scanning Microsoft Fabric and no classifications applied or scan rule sets
Microsoft Purview cannot currently apply built-in or custom classifications (including sensitive information types) to metadata discovered from Microsoft Fabric workspace scans. While Purview can register Fabric workspaces and extract structural metadata (workspaces, Lakehouses, Warehouses, tables, columns, and limited lineage), classification rules are not executed against Fabric assets in the same way they are for supported sources such as Azure SQL, ADLS Gen2, or on-prem databases. This results in classification gaps across a core enterprise analytics platform. Why This Is a Significant Service Omission 1. Breaks the Core Value Proposition of Purview 2. Undermines Regulatory and Risk Management Controls 3. Creates an Inconsistent Governance Experience 4. Blocks Downstream Purview Capabilities 5. Forces Anti-Patterns and Workarounds The lack of automated classification support for Microsoft Fabric workspace data represents a material service omission in Microsoft Purview, significantly limiting its effectiveness as a unified data governance platform and introducing avoidable compliance, operational, and assurance risks—particularly in regulated environments. Are there plans to improve this and if so what are the timescales?
Activity explorer scoping to AU
I remember that Activity Explorer can be fully scoped to Admin Units, and that the Restricted admin can see activity explorer and DLP matching events for the scoped AU only, is that correct? Cause I was checking and I found the Restricted admin can see the activities also for the users out of the scoped AU. Does that make sense?Sharing: PDF readers that support Purview labels
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.
Unable to use MS Graph DLP Api's to use with my Entra Registered App
In purview, I have set of policies in DLP, where I have registered to block the US SSN in the text contents and I have created different policies in all of them I have selected the available locations: Exchange email - All accounts SharePoint sites OneDrive accounts - All accounts Teams chat and channel messages - All accounts Devices - All accounts Microsoft Defender for Cloud Apps On-premises repositories And selected action as block all, in all of them for the rule and enabled the rule (not in simulation mode) Now, I have the app registered in Entra and I try to use the following API's https://learn.microsoft.com/en-us/graph/api/userprotectionscopecontainer-compute?view=graph-rest-1.0 https://learn.microsoft.com/en-us/graph/api/userdatasecurityandgovernance-processcontent?view=graph-rest-1.0&tabs=http But whenever I use the compute api I can see i'm only getting curl -X POST https://graph.microsoft.com/v1.0/users/5fd51e08-c5f1-4298-b79b-a357eaa414ff/dataSecurityAndGovernance/protectionScopes/compute\ -H 'Authorization: Bearer <ACCESS_TOKEN>'\ -H 'Content-Type: application/json' -d '{ "activities": "uploadText,downloadText" }' { "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#Collection(microsoft.graph.policyUserScope)", "value": [ { "activities": "uploadText,downloadText", "executionMode": "evaluateOffline", "locations": [ { "@odata.type": "#microsoft.graph.policyLocationApplication", "value": "b48106d9-1cdb-4d90-9485-fe2b6ee78acf" } ], "policyActions": [] } ] } My sample App's Id is showing up but always with `evaluateOffline` I don't know why it always gives 'evaluteOffline' and policyActions is always empty array Also, I can see my Entra registered app is showing up here in the value of the locations And when I use the processContent api , I always get modified in the response and nothing else like below: curl -XPOST https://graph.microsoft.com/v1.0/users/5fd51e08-c5f1-4298-b79b-a357eaa414ff/dataSecurityAndGovernance/processContent \ -H 'Authorization: <ACCESS TOKEN>'\ -H 'Content-Type: application/json' -d '{ "contentToProcess": { "contentEntries": [ { "@odata.type": "microsoft.graph.processConversationMetadata", "identifier": "07785517-9081-4fe7-a9dc-85bcdf5e9075", "content": { "@odata.type": "microsoft.graph.textContent", "data": "Please process this application for John VSmith, his SSN is 121-98-1437 and credit card number is 4532667785213500" }, "name": "Postman message", "correlationId": "d63eafd2-e3a9-4c1a-b726-a2e9b9d9580d", "sequenceNumber": 0, "isTruncated": false, "createdDateTime": "2026-04-06T00:23:20", "modifiedDateTime": "2026-04-06T00:23:20" } ], "activityMetadata": { "activity": "uploadText" }, "deviceMetadata": { "operatingSystemSpecifications": { "operatingSystemPlatform": "Windows 11", "operatingSystemVersion": "10.0.26100.0" }, "ipAddress": "127.0.0.1" }, "protectedAppMetadata": { "name": "Postman", "version": "1.0", "applicationLocation": { "@odata.type": "microsoft.graph.policyLocationApplication", "value": "b48106d9-1cdb-4d90-9485-fe2b6ee78acf" } }, "integratedAppMetadata": { "name": "Postman", "version": "1.0" } } }' In the above request I have mentioned some sample US Security SSN, but the response I get is { "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#microsoft.graph.processContentResponse", "protectionScopeState": "notModified", "policyActions": [], "processingErrors": [] } But Ideally I want to see whether I can get the content is valid or not, for example in the above request, it has SSN, so ideally I should get restrictAction or something right? Or is that evaluateInline is not available or something? Note that I have purchased E5 and assigned to the user who is trying this Also, whenever I choose to create a Policy in DLP , I got two options And Lets say I choose "Enterprise applications & devices", what happens is in the Locations, I'm seeing only these as the options: And If I choose the "Inline Traffic", i'm seeing only these options In Unmanaged, I'm seeing the following And in the Enforcement Options, I have the following : And in the "Advanced DLP rules" I'm seeing only these So, can you tell me the exact steps in the Purview suite, I couldn't where to mention the Entra registered App, I searched and I couldn't find one But in the compute endpoint, https://learn.microsoft.com/en-us/graph/api/userprotectionscopecontainer-compute?view=graph-rest-1.0 I'm getting my app but only with "evaluateOffline" and with that ETag, If I use the processContent Api, its not giving anything except as I mentioned above in the post
Co Authoring with Sensitivity Labels
Hello, I am working with sensitivity labels with my organization. We currently have Standard, Confidential, and Highly Confidential which all are encrypted. I have Co-Authoring turned on but I have some trouble with. We a lot of documents being collaborated on. Standard: Co-Authoring functions normal and Auto-Save is toggled on. Highly Confidential: Custom Permission in Sensitivity Label (View, Edit, Reply, Forward) I asked copilot and it stated even though my permissions are selected custom I have "Edit" on their for my internal users it is reading it as Co authoring; Co-Authoring is on and functioning but internal end users Auto-Save is toggled off and they are being asked to save a copy of the document or excel sheet then upload it again to SharePoint. Why isn't "Auto-Save" toggled on for "Highly Confidential" label? Can it be adjusted so it can be on? Do I have to make adjustments to my permissions in the Sensitivity label? Any help is appreciated. Thank you!
Guidance: Sensitivity Labels during Mergers & Acquisitions (separate tenants, non-M365, etc.)
We’re building an internal playbook for how to handle Microsoft Purview sensitivity labels during mergers and acquisitions, and I’d really appreciate any lessons learned or best practices. Specifically, I’m interested in how others have handled: Acquired organizations on a separate Microsoft 365/O365 tenant for an extended period (pre- and post-close): How did you handle “Internal Only” content when the two tenants couldn’t fully trust each other yet? Any tips to reduce friction for collaboration between tenants during the transition? Existing label structures, such as: We use labels like “All Internal Only” and labels with user-defined permissions — has anyone found good patterns for mapping or reconciling these with another company’s labels? What if the acquired company is already using sensitivity labels with a different taxonomy? How did you rationalize or migrate them? Acquisitions where the target does not use Microsoft 365 (for example, Google Workspace, on-prem, or other platforms): Any strategies for protecting imported content with labels during or after migration? Gotchas around legacy permissions versus label-based protections? General pitfalls or watch-outs between deal close and full migration: Anything you wish you had known before your first M&A with Purview labels in play? Policies or configurations you’d recommend setting (or avoiding) during the interim period? Any examples, war stories, or template approaches you’re willing to share would be incredibly helpful as we shape our playbook. Thanks in advance for any insights!
