Teams not working on MacOS Big Sur

Anonymous

Hi all, 

I recently installer MacOS Big Sur in my Macbook Pro from scratch (not upgrading from previous installation). Once the system was working, I installed the Office 365 suite from App Store and MS Teams from microsoft.com (Teams does not exists in the App Store). All software is working properly EXCEPT Teams. After installation and launch, I keeps freezed in the "Loading Microsoft Teams" view.

I have uninstalled and reinstalled the package several times, restarted the machine, etc, but it still does not work.

Are there any procedures or fixed I should perform? Does Teams actually works on Big Sur?

Thanks.

    Dear all,

    I just noticed that only the initial startup of a fresh installed version 408872 does fail because it cannot successfully finish the initial setup process.

    Do the following:

    1. install a previous version of Microsoft Teams -I did it with version 333671-
    2. login to your Microsoft Teams account
    3. update to current version

    Now the current version 408872 will work for you on Big Sur 11.3.1

    Bye

    This worked perfectly (after a lot of trials with the other, more cumbersome solutions). I kept getting a looping error-message about Planner and To Do, and could not get past it. However, opening a meeting in my calendar app and enter through there, solved the problem. Interesting that Microsoft not yet has solved the issue.

    Hi Rodrigo,

    I'm Nik, an independent advisor here to assist you with this.

    1. Quit Microsoft Teams.
    2. Delete files in following folders.
      “~/Library/Application Support/Microsoft/Teams/Application Cache/Cache”
      “~/Library/Application Support/Microsoft/Teams/blob_storage”
      “~/Library/Application Support/Microsoft/Teams/Cache”
      “~/Library/Application Support/Microsoft/Teams/databases”
      “~/Library/Application Support/Microsoft/Teams/GPUCache”
      “~/Library/Application Support/Microsoft/Teams/IndexedDB”
      “~/Library/Application Support/Microsoft/Teams/Local Storage”
      “~/Library/Application Support/Microsoft/Teams/tmp”
    3. Restart Microsoft Teams.

    If it does not work, you may try clearing the cache of your app.
    Sign Out and Quit Microsoft Teams then
    to remove the cache credentials.
    See following steps：

    1. Go to Finder > Applications > Utilities.
    2. Select Keychain Access.
    3. Look for the login credential to MS teams, then delete it.

    Regards
    Nik

    THIS WORKS! This is the only method that works after trying all other methods. Especially the Keychain Access part is the one does the trick! Thank you!

    Hi Rodrigo,

    For troubleshooting purpose please make sure you disable Firewall, Antivirus, VPN/Proxy for a while.

    If you have any other device and check the outcome, it will help us to isolate issue with your account and device used.

    Regards
    Nik
