Insider Risk Level not being correctly picked up by DLP
I have two users currently with assigned Insider Risk levels, one elevated and one minor. I have taken the templated DLP policy (DSPM for AI - Block sensitive info from AI sites) which looks for sensitive information being pasted to generative AI sites, and applies a block if the user is an elevated risk user, and a block with override for a moderate/minor risk user (this was audit only originally). For each advanced DLP rule within that policy, I have a separate policy tip which shows so I know which Advanced DLP rule has been hit. However, I'm having some discrepancies with the correct insider risk level being identified by Purview and therefore the wrong advanced DLP rule is being applied. Testing examples: Logged into a Windows 11 PC with the account, and using Medium confidence UK NINO's I try pasting the content into ChatGPT: Elevated risk user: Block with Override Minor Risk user: Block with Override If I try the exact same scenario on a different PC, I can sometimes get to the point where even though its the same set of data, Purview allows me to paste it at after checking the data. Or in another scenario, I was getting both users hitting the "elevated risk" advanced DLP rule. The Devices are all showing as up to date sync wise with DLP policies, and the policy itself is showing as fully synced. Assigned insider risk levels: DLP Rules: Elevated: Moderate/Minor:
Onboarding Devices to Purview
I am not clear on how can I onboard devices to MDE so that I can enforce EDLP policies. We have CrowdStrike as Primary AV and other policies. Devices are managed through Intune for Bitlocker encryption and all the other settings except they don't have Defender. These devices are not showing up in Purview nor under "Endpoint detection and response" location under Endpoint Security. If we create an EDR onboarding policy and deploy to devices, then it shows the devices and says that AMRUnningMode is Passive, but Antivirus is true. Which I feel like Defender is taking over CrowdStrike? or am I wrong. My goal is to make sure CrowdStrike still primary AV and devices should be onboarded to MDE and then to Purview so that we can scope EDLP policies properly. Can anyone help me to understand or provide right steps?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.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?
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
Email to external(trusted user) not require verify user Identity(with Google or One-time passcode)
Dear Expert and Community, I am starting with MS Purview - Data Loss Prevention. I have one point to clarify and seek your advise / comment / contribute or sharing good practice regarding with below: - Firstly, we can send email to externally user contain sensitive information, it is encryption or blocked (result: worked as expected). If remail encrypt, the external receiver require verify the Identity via sign in with google acc / with a one time password. - Second: we plan sending email to external user (only trusted user / domain). Is it possible, do not require these scope user reverify their Identity again and again? If yes, how to do it? If not - why? Well appreciated for update and supporting. Thanks,
Test DLP Policy: On-Prem
We have DLP policies based on SIT and it is working well for various locations such as Sharepoint, Exchange and Endpoint devices. But the DLP policy for On-Prem Nas shares is not matching when used with Microsoft Information Protection Scanner. DLP Rule: Conditions Content contains any of these sensitive info types: Credit Card Number U.S. Bank Account Number U.S. Driver's License Number U.S. Individual Taxpayer Identification Number (ITIN) U.S. Social Security Number (SSN) The policy is visible to the Scanner and it is being logged as being executed MSIP.Lib MSIP.Scanner (30548) Executing policy: Data Discovery On-Prem, policyId: 85........................ and the MIP reports are listing files with these SITs The results Information Type Name - Credit Card Number U.S. Social Security Number (SSN) U.S. Bank Account Number Action - Classified Dlp Mode -- Test Dlp Status -- Skipped Dlp Comment -- No match There is no other information in logs. Why is the DLP policy not matching and how can I test the policy ? thanksTeams 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.DLP USB Block
Currently we have DLP policies setup to block the use of USB devices and copying data to it. When checking the activity explorer I am still seeing user's able to copy data to USB devices and for the action item it says "Audit" when in the DLP policies we explicitly set it to block. Has anyone run into this issue or seen similar behavior?
