Encryption disappears in Outlook - Sensitivity Label not working
Hello everyone, we implemented Sensitivity Labels at our client and have iconsistent and unexpected behavior, we cannot explain. Maybe some of you can help or have ideas on whats going on: Scenario / Use Case A customer is using Sensitivity Labels to encrypt emails in Exchange Online. Label configuration: The sensitivity label applies encryption The label is scoped (published) to a Microsoft 365 group User A and User B are members of this Microsoft 365 group and therefore can apply the label User are licensed with M365 Business Premium The label is published and available to User A and User B (member of above M365 group) User C is an external recipient and not included in the label’s publishing scope Observed Behaviors Scenario 1 – Encryption Lost When Forwarded Externally User A (internal) sends an email to User B (internal) using a sensitivity label that applies encryption. User B receives the email correctly: The lock icon in Outlook is displayed, the message is encrypted as expected User B forwards the email to User C (external) User C receives the forwarded email unencrypted: No lock icon is shown, User C can read the entire conversation history, including content that was previously encrypted Scenario 2 – Encryption Disappears Within an Internal Email Conversation In addition to the external forwarding scenario, we are also observing the following behavior within an internal email thread: User A sends an encrypted email to User B using the sensitivity label. User B replies to User A: The reply remains encrypted User A replies again within the same conversation Suddenly, the encryption disappears: The lock icon is no longer shown The message and the full conversation history is no longer protected This happens without any user action to remove or change the sensitivity label. Key Observation Both scenarios occur intermittently: Sometimes encryption behaves as expected Sometimes encryption disappears “out of nowhere” The behavior is not reliably reproducible, which makes troubleshooting very difficult. Any help is appreciated!
DLP 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.Can´t Sign confidential documents
Hello, I have a problem. I want to send confidential contracts to customers for signing with Adobe DocuSign. This contracts have a label "confidential" from purview and are encrypted. But now the customer cant sign the contract with DocuSign because of the encryption. Is there a way that they can sign the document? We must encrypt the documents because compliance reasons and ISMS. Thank you.
Two 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!Label group migration - existing files labelled with former parent labels
Hi, I have a question about behavior during migration from legacy parent labels to label groups. Historically, we were allowed to apply parent labels directly to content. In our environment, we have an existing parent label called PUBLIC which has sublabels. PUBLIC itself has content encryption configured, so during migration it will be recreated as a sublabel within a label group. As a result, there are existing files that are currently labelled simply as PUBLIC (applied back when parent labels could be used directly). Post-migration, we plan to de-publish this newly created PUBLIC sublabel from user-facing policies. My question is about what happens to those existing files during and after the migration. Will files that are already labelled as PUBLIC automatically be updated to a specific label within the label group, such as PUBLIC/PUBLIC, or will they remain labelled as PUBLIC with no automatic relabelling? In other words, does the label group migration perform any automatic relabelling of existing content, or does it only affect label structure and publication going forward?Justification not triggered when downgrading between sublabels under same parent label
Hi all, I am looking for confirmation of expected behaviour with Microsoft Purview sensitivity labels and justification. We have justification enabled in our sensitivity label policy. When a user changes a label between labels that belong to the same label group, no justification prompt appears. When a user changes from a label in one label group to a label in a different label group, the justification prompt does appear as expected. Is this behavior by design? Specifically, does Microsoft treat the label group as the enforcement boundary for downgrade justification, meaning justification is not evaluated when moving between labels within the same group, even if effective protection is reduced? If this is expected, is there any supported way to require justification when downgrading between labels in the same label group? Thank you!
Block transfer of labelled data through CLI Apps - Powershell
I have a ticket open with microsoft since mid november, and to date not fixed, still chasing. So we have labelled data, using a custom label intellectual property. We block and alert using it, from uploads to list of urls, to prompt to override, etc. So the label works. Next step is to prevent exfil using Cli apps. This is where the issue is.. Not working. Would you have any idea if this actually works? Has anyone set it up? In settings and then Restricted apps and app groups I have setup the following: Then I created a policy that is applied to my machine and my user to block the move and upload of data that is labelled as Intellectual Property (Sensivity Label) It should block when I am using WinSCP or powershell. It does not. I tried with the restricted app group and with access by restricted apps. None works My machine is in sync
Data Quality Error (Internal Service Error)
I am facing an issue while running the DQ scan, when i tried doing manual scan and scheduled scans both time i faced Internal Service Error. ( DataQualityInternalError Internal service error occurred .Please retry or contact Microsoft support ) Data Profiling is running successfully but for none of the asset, DQ is working. After the lineage patch which MS had fixed, they had introduced Custom SQL option to create a rule, and after that only i am facing this issue. Is anyone else also facing the same? I tried with different data sources (ADLS, and Synapse) its same for both. If anyone has an idea, do share it here, it will be helpful.
