Chat channel - removed user can still see all new messages

[MHTECH08]

Hi

Reoccurring meeting, user got added to this meeting.

Once meeting was finished this user got removed. A few days later the same meeting took place, the removed user could see all the new messages etc.

The user is not part of the participants for the current meeting or the chat channel. They weren't part of the original meeting invite either.

Any suggestions please?

@MHTECH08Does the problem persist if the users log in through the web application? If not, then the problem is local and I would recommend deleting the local Teams files on the users computer and reinstall the app.
If it does persist, then I guess it's a bugg from Microsoft and I am as helpless as you are
