If you use Microsoft Teams, you know that you send messages to a Teams meeting before, during and after the meeting.
Well, to help avoiding potential data leak from Teams meeting chats, a new policy is now available to disable ability to send chat messages to Teams meeting before and after this meeting for specific peoples (everyone or anonymous only).
To turn this option, connect to your Teams administration portal (https://admin.teams.microsoft.com/) to access the Meetings policies.
NOTE the way to access the Meetings policies may vary depending if you have turn on the new experience settings and policies view
Once connected, access the Meetings policies either from the Settings & policies\Meetings blade (new) or Meetings\Meeting policies blade to edit the Meeting engagement option
