The reported message along with the preceding five messages will be reviewed by an internal reviewer assigned by the organization. 

Furthermore, when a user reports a message and submit it to Microsoft, the message content, files, URLs, message headers, and everything related to the message are copied for continual algorithm review. Microsoft considers that as permission from your organization for enhancing the message hygiene algorithms. And the submissions are deleted by Microsoft soon after their requirement is unneeded.

  • A user can report a message multiple times. 
  • The reported messages are not notified to their respective senders.

Reviewing Reported Teams Messages in Microsoft 365 

Besides monitoring in the Microsoft 365 Defender portal, these user-reported Teams messages can be efficiently reviewed under the User-reported messages policy in the Microsoft Purview Communication Compliance portal. The only setting you can configure in this user-reported message policy is assigning reviewers for the reported messages.  

However, the pending tab under user reported messages policy covers the user-reported messages including their summary, conversation, source, and user history to understand the issue better. Based on the investigation, the reviewer can remove the message from the chat.
