Hi, I am working on implementing security measures for Microsoft Copilot in a client environment. I want to create a DLP policy to not process data with certain sensitivity labels but when I go into DLP to create the policy, the location for Microsoft 365 Copilot is not an option. I also noticed that the "Fabric and Power BI workspaces: location is also not available. I have checked other similar client M365 tenants, and both of these locations are available by default. Any insight would be appreciated.606Views0likes5CommentsAdaptive Scopes
I'm setting up adaptive scopes in MS Purview for data retention testing, focusing on Entra groups. However, when I create a test adaptive scope using the 365 groups scope and add a query with the group's display name, it doesn't populate. Some scopes are over 7 days old, despite MS stating it can take up to 3 days for queries to sync. Does anyone have a better method for creating adaptive scopes for Entra groups?360Views0likes4CommentsDLP Policy - DSPM Block sensitive info from AI sites
Having issues with this DLP policy not being triggered to block specific SITs from being pasted into ChatGPT, Google Gemine, etc. Spent several hours troubleshooting this issue on Windows 11 VM running in Parallels Desktop. Testing was done in Edge. Troubleshooting\testing done: Built Endpoint DLP policy scoped to Devices and confirmed device is onboarded/visible in Activity Explorer. Created/edited DLP rule to remove sensitivity label dependency and use SIT-based conditions (Credit Card, ABA, SSN, etc.). Set Paste to supported browsers = Block and Upload to restricted cloud service domains = Block in the same rule. Configured Sensitive service domain restrictions and tested priority/order (moved policy/rule to top). Created Sensitive service domain group for AI sites; corrected entries to hostname + prefix wildcard a format (e.g., chatgpt.com + *.chatgpt.com) after wildcard/URL-format constraints were discovered. Validated Target domain = chatgpt.com in Activity Explorer for paste events. Tested multiple SIT payloads (credit card numbers with/without context) and confirmed detection occurs. Confirmed paste events consistently show: Policy = Default Policy, Rule = JIT Fallback Allow Rule, Other matches = 0, Enforcement = Allow (meaning configured rules are not matching the PastedToBrowser activity). Verified Upload enforcement works: “DLP rule matched” events show Block for file upload to ChatGPT/LLM site group—proves domain scoping and endpoint enforcement works for upload. Disabled JIT and retested; paste events still fall back to JIT Fallback Allow Rule with JIT triggered = false. Verified Defender platform prerequisites: AMServiceVersion (Antimalware Client) = 4.18.26020.6 (meets/exceeds requirements).96Views0likes6CommentsTeams Private Channels Reengineered: Compliance & Data Security Actions Needed by Sept 20, 2025
You may have missed this critical update, as it was published only on the Microsoft Teams blog and flagged as a Teams change in the Message Center under MC1134737. However, it represents a complete reengineering of how private channel data is stored and managed, with direct implications for Microsoft Purview compliance policies, including eDiscovery, Legal Hold, Data Loss Prevention (DLP), and Retention. 🔗 Read the official blog post here New enhancements in Private Channels in Microsoft Teams unlock their full potential | Microsoft Community Hub What’s Changing? A Shift from User to Group Mailboxes Historically, private channel data was stored in individual user mailboxes, requiring compliance and security policies to be scoped at the user level. Starting September 20, 2025, Microsoft is reengineering this model: Private channels will now use dedicated group mailboxes tied to the team’s Microsoft 365 group. Compliance and security policies must be applied to the team’s Microsoft 365 group, not just individual users. Existing user-level policies will not govern new private channel data post-migration. This change aligns private channels with how shared channels are managed, streamlining policy enforcement but requiring manual updates to ensure coverage. Why This Matters for Data Security and Compliance Admins If your organization uses Microsoft Purview for: eDiscovery Legal Hold Data Loss Prevention (DLP) Retention Policies You must review and update your Purview eDiscovery and legal holds, DLP, and retention policies. Without action, new private channel data may fall outside existing policy coverage, especially if your current policies are not already scoped to the team’s group. This could lead to significant data security, governance and legal risks. Action Required by September 20, 2025 Before migration begins: Review all Purview policies related to private channels. Apply policies to the team’s Microsoft 365 group to ensure continuity. Update eDiscovery searches to include both user and group mailboxes. Modify DLP scopes to include the team’s group. Align retention policies with the team’s group settings. Migration will begin in late September and continue through December 2025. A PowerShell command will be released to help track migration progress per tenant. Migration Timeline Migration begins September 20, 2025, and continues through December 2025. Migration timing may vary by tenant. A PowerShell command will be released to help track migration status. I recommend keeping track of any additional announcements in the message center.973Views2likes1CommentDLP for SaaS Apps - Endpoint DLP/MDE + Purview Browser Extension
I need help verifying my understanding of how Purview tools control file upload/download and clipboard copy/paste actions. Here's the situation: Goal: Block file upload/download, copy/paste of sensitive data to/from SaaS apps. Deployment: Rolling out MDE (in Passive mode) or Endpoint DLP (Onboarding device to Purview) and the Purview browser extension for Chrome/Firefox. My Understanding: Copy Control: Handled by Endpoint DLP/MDE on the endpoint. Upload/Download/Paste Control: Requires the Purview browser extension (or native browser support Edge/Safari). Specific Question: The browser extension isn't available for macOS. I've read that MDE on macOS can handle everything (file upload/download and clipboard control). Could someone confirm if the table I've created correctly reflects this? Summary of Clipboard (Copy/Paste) Enforcement Operation Windows (Onboarded) macOS (Onboarded) Note Copy to Clipboard Endpoint Endpoint DLP Sensor Endpoint DLP Sensor Prevents data from reaching the clipboard Paste into SaaS Apps (Chrome/Firefox) Browser Extension Endpoint DLP Sensor Blocks paste into SaaS apps. Paste into SaaS Apps (MS Edge/Safari) Native on Edge Native on Edge/Safari Built-in integration; no extension needed.314Views1like2CommentsTwo sensitivity labels on PDF file
Hi everyone, First time poster here. We encountered an interesting issue yesterday where we had a user come to us with a PDF that had two sensitivity labels attached. In Purview activity explorer, we can see the file hit the DLP policy and the two labels, but when trying to replicate the issue cannot do it, or see how this has been done. Has anyone else encountered a similar issue? We were able to remove labels in our PDF editor but in Office suite once a label is applied, I could not see a way to remove it. We tried applying a label to a Doc file, converting to PDF and then seeing if it was there where it was being asked for another label but it was not, it just let us change the original. Many thanks in advance!305Views0likes3CommentsMigrating DLP Policies from one tenant to other
Has anyone successfully migrated DLP policies from a dev tenant (like contoso.onmicrosoft.com) to a production tenant (paid license with custom domain) in Microsoft Purview without third-party tools? We're open to using PowerShell, Power Automate, or other Microsoft technologies—such as exporting policies via PowerShell cmdlets from the source tenant, then importing/recreating them in the target tenant using the Microsoft Purview compliance portal or Security & Compliance PowerShell module. Details: The dev tenant has several active DLP policies across Exchange, Teams, and endpoints that we need to replicate exactly in prod, including sensitive info types, actions, and conditions. Is there a built-in export/import feature, a sample script, or Power Automate flow for cross-tenant migration? Any gotchas with licensing or tenant-specific configs?Solved430Views0likes4CommentsCopilot DLP Policy Licensing
Hi everyone We are currently preparing our tenant for a broader Microsoft 365 Copilot rollout and in preparation to that we were in the progress of hardening our SharePoint files to ensure that sensitive information stays protected. Our original idea was to launch sensitivity labels together with a Purview data loss prevention policy that excludes Copilot from accessing and using files that have confidential sensitivity labels. Some weeks ago when I did an initial setup, everything worked just fine and I was able to create the before mentioned custom DLP policy. However, when I checked the previously created DLP policy a few days back, the action to block Copilot was gone and the button to add a new action in the custom policy is greyed out. I assume that in between the initial setup and me checking the policy, Microsoft must have moved the feature out of our licensing plan (Microsoft 365 E3 & Copilot). Now my question is what the best licensing options would be on top of our existing E3 licences. For cost reasons, a switch to Microsoft 365 E5 is not an option as we have the E3 licences through benefits. Thanks!Solved696Views0likes2CommentsDLP Policy Matches
I am trying to created conditions in our test policy to only scan outgoing emails from our domain and ignore incoming emails from external parties. In the conditions I am trying to make sure I select the correct one. I do see a condition "Sender domain is" would this condition only scan for emails coming from our domain (example.com) and ignore all other incoming emails?Solved227Views0likes2Comments
