Sensitivity Labels and CoPilot - "No AI"
As a Purview Administrator, I recently received a request that might resonate with many of you: add a “No AI” designation to every sublabel we have. Why? Because our contracts and EULAs explicitly state that certain documents must not be used with AI tools. This raises an important question: What’s the best way to implement this without creating unnecessary complexity? The Challenge If we simply append “NoAI” to every existing label and sublabel, we end up duplicating our entire labeling structure. For example, if you follow Microsoft’s guidance on default sensitivity labels and policies, doing this “times two” for every label and sublabel is clearly not scalable. How do you deploy it? Best regards Stephan
Issue with the Canadian Drivers License SIT
Did any face an issue with the Canadian Driver's License SIT in the DLP policy? We see a lot of false positives especially around BC province number, NB, PrinceEdward Island and Saskatchewan. These provinces has just digits which can flag any kind of digits. Even if we use some custom RegEx and reduced keyword list, it still flags a lot of false positives. We see this as more and more customers are not happy with it. Has anyone found a breakthrough or best solution for deploying the Canadian Driver's License DLP?
Need help with DLP Policy in Purview
One of our requirements is to block Copilot from discovering or querying internal files. Specifically, files labeled Internal or Confidential should not be discoverable or accessible by Copilot. I was able to obtain some step-by-step instructions from Copilot, but the required settings do not appear in our Purview portal, likely due to our E3 licensing. Has anybody created a DLP policy to achieve this or do you have a
Auto-Label Simulation does not simulate your rules exactly
When you’re building an auto-labeling rule and run a simulation, don’t expect it to fully follow your rule. Let me explain. It doesn’t evaluate everything. For example, if your rule says a document must match at least four regex patterns to count as a positive find, the simulation might treat a single match as a positive. Yeah, that’s frustrating. Here’s what works better: Build your Sensitive Information Type (SIT) and test it against individual documents first. Then create a policy that targets a small subset of data. Run the simulation, then turn on the policy. Check the results in Activity Explorer, which shows real production activity. Why can’t the simulation just run the full rule? Good question—we all wish it did.
Purview-Retention Policy for Private channels
I have retention policy for Standard & Shared channels together with 2 Years retention period to keep posts for 2 years and remove after that period. Don’t have any policy for Private channels posts/messages, so posts will be available indefinitely . With this https://www.microsoft.com/en-in/microsoft-365/roadmap?id=500380from Microsoft my private channels will also part of the same policy which is applied for standard & Shared channels . in this case how i can retain the posts from private channels indefinitely . Please suggest
Some Fabric Lakehouse tables not appearing in Microsoft Purview after scan
Hi everyone, I’m running into an issue where several tables from a Fabric Lakehouse aren’t appearing in Microsoft Purview after a workspace scan. Here’s the situation: I scanned a Fabric workspace that contains multiple Lakehouses. For most Lakehouses, the tables appear correctly in Purview after the scan. However, for one specific Lakehouse, several tables that I know exist aren’t showing up in the scanned assets — even after adding the Lakehouse as an asset to a data product in the Unified Catalog. What I’ve tried: I rescanned the workspace and the specific Lakehouses. I verified that the tables are persistent (not temporary) and appear under the Tables section in Fabric, not only as files. I confirmed permissions for the Purview connection account. Scan results and errors: After the rescan, the tables still didn’t appear. The scan logs show several ingestion errors with messages like: Failed to ingest asset with type fabric_lakehouse and qualified name [qualified name] due to invalid data payload to data map I checked the error entries to see which assets they point to, and none of them are related to the tables in the Lakehouse in question. There were four of these errors in the last run. Additional context: Some older Lakehouses that had been archived months ago in Fabric still appeared as active in Purview before the rescan, so there may be stale metadata being retained. Notes: I’m aware Fabric scanning in Purview currently has sub-item scanning limitations where item-level metadata is prioritised, and individual tables aren’t always picked up. But given that tables from other Lakehouses appear as expected, and given the ingestion errors (even though the errors do not point to the missing tables), it feels like there may be a metadata sync or processing issue rather than a simple coverage limitation. Question: Has anyone encountered this behaviour or the “invalid data payload to data map” error before? Any guidance on further troubleshooting steps would be appreciated. Thanks in advance!How to offboarding endpoint from Purview
Hi I'm a fresh user of Purview and after creating policies linked to Exchange, I've enabled the onboarding of computer. Unfortunately, all Defender endpoints have been onboarded, and I've not be able to define which one was concerned. Now, I would like to offboard all those devices from purview and only keep them in Defender without any DLP protection. I tried to remove them with the onboarding script, but my endpoints are still present in Purview. How can I completely remove them? Thanks for your help YohannDuplicate file detection
Hi Community, I need to scan multiple windows file servers using Microsoft Purview and one of the asks is to detect and identify duplicate files on those. Can someone please guide how that can be accomplished. What functionality needs to be used and how to go about duplicate detection? Note that this is primarily duplicate finding assignment for files as in office documents and pdfs. Thanks.
