Purview DLP Policy - Exchange -Policy to block passwords in email matching Teams meeting invitation

Julien 5

Hi,

We set-up a DLP Policy targeting Exchange location. The goal is to block emails containing Password (we are leveragring the "General Password" built-in SIT).

Policy is working great, but it is also blocking Teams Meeting Invitation as they do contain Meeting ID and Passcode information, and passcode is flaged by the General Password SIT.

We excluded meeting invitation from the policy as a temporary solution, but it is not a good solution as users can still write passwords in the invitation.

Is there a possibility to specificaly exclude Teams meeting invitation from the Policy and not only meeting invitation ?

Thanks for your help !

Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!

Is there a possibility to specificaly exclude Teams meeting invitation from the Policy and not only meeting invitation ?

Yes, it is possible to specifically exclude Teams meeting invitations from your DLP policy in Microsoft Purview while still enforcing the policy on other types of meeting invitations and emails. To specifically exclude Teams meeting invitations from your DLP policy while still enforcing password protection in other emails. Here are the steps:

Identify Unique Elements - Look for specific phrases and formatting that are unique to Teams meeting invitations, such as: "Join Microsoft Teams Meeting" "Meeting ID" "Passcode" Links that start with "https://teams.microsoft.com/"

Modify Your DLP Policy - Access the DLP policy in the Microsoft Purview compliance portal and edit the policy you have set up. Add conditions that specifically look for the unique phrases or patterns identified above.

Set Up Conditional Exclusions - For example, you can create a condition that excludes emails containing: "Join Microsoft Teams Meeting" "Meeting ID" "Passcode" This way, the DLP policy will not apply to Teams meeting invitations while still protecting against password sharing in other contexts.

Testing and Monitoring - After making these changes, test the policy with a small group of users to ensure that legitimate Teams meeting invitations are not being blocked. Monitor the policy's effectiveness and adjust as necessary.

By implementing these targeted exclusions, you can maintain the security of your email communications without disrupting the functionality of Teams meeting invitations.

I hope this information helps.
