The Microsoft Graph PowerShell SDK and the additionalProperties Property
The additionalProperties property is available for many Microsoft Graph PowerShell SDK cmdlets. In this article, we explain the function of the additionalProperties property and how it functions in holding output for Microsoft Graph PowerShell SDK cmdlets. It’s all because of the lack of strongly-typed properties, or so the AutoRest process would have us believe. https://office365itpros.com/2026/04/21/additionalproperties-property/Automating Microsoft 365 with PowerShell Second Edition

A reader wanted a weekly incomplete task report to send details of Planner tasks to people with outstanding work to do. We used PowerShell to scan for incomplete tasks for people who are members of a group, perform some analysis on the data, and create and send email. Despite some deficiencies in the Planner Graph API, the code is pretty straightforward. https://office365itpros.com/2026/04/15/weekly-incomplete-task-report/
Microsoft Graph: Private channel SharePoint site URL naming appears to have changed
📄 Question We are creating private channels using the Microsoft Graph API: POST https://graph.microsoft.com/v1.0/teams/{team-id}/channels With the following payload: { "@odata.type": "#microsoft.graph.channel", "displayName": "Project-Channel-001", "description": "Sample private channel for testing", "membershipType": "private", "members": [ { "@odata.type": "#microsoft.graph.aadUserConversationMember", "******@odata.bind": "https://graph.microsoft.com/v1.0/users/{user-id}", "roles": ["owner"] } ] } 🔍 Observed Behavior When the private channel is created, the associated SharePoint site is provisioned automatically (as expected). However, the URL format appears to have changed. Previously observed behavior: https://{tenant}.sharepoint.com/sites/ProjectTeamURL-Project-Channel-001 Current behavior: https://{tenant}.sharepoint.com/sites/ProjectTeamName-Project-Channel-001 ❗ Impact This change introduces several issues: Breaks deterministic URL generation logic Produces longer and less predictable URLs Introduces dependency on display name, which is mutable and may contain unexpected characters Impacts existing automation and integrations relying on the previous pattern ❓ Questions Has there been a recent change in how SharePoint site URLs are generated for private channels? Is this behavior intentional and documented, or a regression? Is there any way (via Graph or otherwise) to: Control the generated SharePoint site URL, or Retrieve the final site URL deterministically without relying on pattern assumptions? Is the previous {ParentTeamUrl}-{ChannelName} format still expected in some scenarios, or has it been deprecated? 🧪 Additional Notes This behavior is observed when creating channels via Microsoft Graph (v1.0) The issue is reproducible across multiple test scenarios 🙏 Any clarification from Microsoft or others encountering this would be appreciated.Restricting App Creation of SharePoint Online Sites
This article discusses the use of restricted site creation for third-party Entra ID apps. The feature has an allow or deny list to identify apps that can create new SharePoint Online sites. Controlling the set of apps that can create new sites contributes to limiting site sprawl and makes sure that every site has a real function. First-party apps like Teams are unaffected. https://office365itpros.com/2026/04/02/restricted-site-creation-apps/Microsoft 365 & Power Platform Community call

Intune – Unable to reliably validate application installation status via Microsoft Graph APIs
Hi Everyone, I am working on application deployment and validation using Microsoft Intune, and I am trying to implement an automated validation step to confirm whether applications are successfully installed. My primary requirement Verify application installation status Confirm per‑device installation status Validate installation for specific Intune‑managed devices Use Graph APIs as part of an automation workflow APIs tested so far 1️⃣ App installation status per device (NOT working / not usable) I initially tried using the documented API: HTTP GET https://graph.microsoft.com/beta/deviceAppManagement/mobileApps/{mobileAppId}/deviceStatuses Issue: This API is not working for us It either returns no data or behaves as if it is not a valid / usable endpoint It does not return reliable installation status Hence, we cannot use this API for validation in automation At this point, deviceStatuses is not usable as a primary source of truth in our environment. 2️⃣ Detected Apps (secondary confirmation only) We are also using the Detected Apps API: HTTP GET /deviceManagement/managedDevices/{deviceId}/detectedApps This does work, however: It only confirms app presence It does not confirm Intune assignment or installation intent We are using it strictly as a secondary confirmation, not a primary validation method 3️⃣ Intune internal API observed via browser inspection We also tested the API that appears to be used internally by the Intune portal: HTTP GET https://graph.microsoft.com/beta/users/{user-id}/mobileAppIntentAndStates/{device-id} Observations: The API returns data However, installState frequently shows unknown The Intune portal shows a different and final status (Installed / Failed / Pending) This makes the API unreliable for automation It appears to be troubleshooting‑oriented, not intended for reporting or validation Questions I am looking for guidance on Is deviceStatuses known to be unreliable, tenant‑dependent, or effectively unsupported? What is the recommended API to retrieve actual app installation status per device? Are there any v1.0 APIs available for: Device‑level app installation status? User‑level app installation validation? What is Microsoft’s recommended best practice to validate Intune‑installed applications via automation? Is there official documentation that clearly explains: Which API should be used for reporting vs troubleshooting Expected delays or data inconsistencies between Graph APIs and the Intune portal Goal The goal is to build a reliable and supported automation‑based validation mechanism to confirm that Intune‑deployed applications are successfully installed on target devices. Any official guidance, confirmation of known limitations, or alternative approaches would be very helpful. Thanks in advance for your support.I built a free, open-source M365 security assessment tool - looking for feedback
I work as an IT consultant, and a good chunk of my time is spent assessing Microsoft 365 environments for small and mid-sized businesses. Every engagement started the same way: connect to five different PowerShell modules, run dozens of commands across Entra ID, Exchange Online, Defender, SharePoint, and Teams, manually compare each setting against CIS benchmarks, then spend hours assembling everything into a report the client could actually read. The tools that automate this either cost thousands per year, require standing up Azure infrastructure just to run, or only cover one service area. I wanted something simpler: one command that connects, assesses, and produces a client-ready deliverable. So I built it. What M365 Assess does https://github.com/Daren9m/M365-Assess is a PowerShell-based security assessment tool that runs against a Microsoft 365 tenant and produces a comprehensive set of reports. Here is what you get from a single run: 57 automated security checks aligned to the CIS Microsoft 365 Foundations Benchmark v6.0.1, covering Entra ID, Exchange Online, Defender for Office 365, SharePoint Online, and Teams 12 compliance frameworks mapped simultaneously -- every finding is cross-referenced against NIST 800-53, NIST CSF 2.0, ISO 27001:2022, SOC 2, HIPAA, PCI DSS v4.0.1, CMMC 2.0, CISA SCuBA, and DISA STIG (plus CIS profiles for E3 L1/L2 and E5 L1/L2) 20+ CSV exports covering users, mailboxes, MFA status, admin roles, conditional access policies, mail flow rules, device compliance, and more A self-contained HTML report with an executive summary, severity badges, sortable tables, and a compliance overview dashboard -- no external dependencies, fully base64-encoded, just open it in any browser or email it directly The entire assessment is read-only. It never modifies tenant settings. Only Get-* cmdlets are used. A few things I'm proud of Real-time progress in the console. As the assessment runs, you see each check complete with live status indicators and timing. No staring at a blank terminal wondering if it hung. The HTML report is a single file. Logos, backgrounds, fonts -- everything is embedded. You can email the report as an attachment and it renders perfectly. It supports dark mode (auto-detects system preference), and all tables are sortable by clicking column headers. Compliance framework mapping. This was the feature that took the most work. The compliance overview shows coverage percentages across all 12 frameworks, with drill-down to individual controls. Each finding links back to its CIS control ID and maps to every applicable framework control. Pass/Fail detail tables. Each security check shows the CIS control reference, what was checked, what the expected value is, what the actual value is, and a clear Pass/Fail/Warning status. Findings include remediation descriptions to help prioritize fixes. Quick start If you want to try it out, it takes about 5 minutes to get running: # Install prerequisites (if you don't have them already) Install-Module Microsoft.Graph, ExchangeOnlineManagement -Scope CurrentUser Clone and run git clone https://github.com/Daren9m/M365-Assess.git cd M365-Assess .\Invoke-M365Assessment.ps1 The interactive wizard walks you through selecting assessment sections, entering your tenant ID, and choosing an authentication method (interactive browser login, certificate-based, or pre-existing connections). Results land in a timestamped folder with all CSVs and the HTML report. Requires PowerShell 7.x and runs on Windows (macOS and Linux are experimental -- I would love help testing those platforms). Cloud support M365 Assess works with: Commercial (global) tenants GCC, GCC High, and DoD environments If you work in government cloud, the tool handles the different endpoint URIs automatically. What is next This is actively maintained and I have a roadmap of improvements: More automated checks -- 140 CIS v6.0.1 controls are tracked in the registry, with 57 automated today. Expanding coverage is the top priority. Remediation commands -- PowerShell snippets and portal steps for each finding, so you can fix issues directly from the report. XLSX compliance matrix -- A spreadsheet export for audit teams who need to work in Excel. Standalone report regeneration -- Re-run the report from existing CSV data without re-assessing the tenant. I would love your feedback I have been building this for my own consulting work, but I think it could be useful to the broader community. If you try it, I would genuinely appreciate hearing: What checks should I prioritize next? Which security controls matter most in your environment? What compliance frameworks are most requested by your clients or auditors? How does the report land with non-technical stakeholders? Is the executive summary useful, or does it need work? macOS/Linux users -- does it run? What breaks? I have tested it on macOS, but not extensively. Bug reports, feature requests, and contributions are all welcome on GitHub. Repository: https://github.com/Daren9m/M365-Assess License: MIT (free for commercial and personal use) Runtime: PowerShell 7.x Thanks for reading. Happy to answer any questions in the comments.
Allow addition of members to mail-enabled security groups via Graph API
Previously one could add members to mail-enabled security groups via Graph API. But turns out that was a bug, and it was fixed some weeks ago removing this functionality. Would it be possible to allow add-remove of members in mail-enabled security groups via Graph API?
