    Hi @walid issa

    Does anyone else have the same issue in your organization?

    Have you tried to login Teams web client to see if it can be reproduced?

    A 401 Unauthorized error on the Microsoft Teams desktop app specifically points towards an issue with user permissions or authentication. Here are some steps the users can take to troubleshoot the problem:

    1. Update Teams App: Ensure users have the latest version of the Teams app installed. Updates often include bug fixes and security improvements.
    2. Restart Devices: A simple device restart can sometimes resolve temporary glitches that might be causing the error.
    3. Sign Out and Sign Back In: A simple sign-out and sign-back in can sometimes refresh the user's credentials and resolve temporary permission issues.
    4. Check Internet Connection: Ensure users have a stable internet connection. A faulty connection can disrupt authentication processes.
    5. Clear Teams Cache: Corrupted cache data might be causing problems.
