Teams not working on MacOS Big Sur

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.

    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

    Thank you Nik.

    Unfortunately, none of the methods worked to make Teams work. It keeps on this view. Are there any others methods I could try? This is mi work laptop and Teams is the main remote tool we use. I am considering to downgrade MacOS to make it work.

    Thanks for the help.

    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

    I am having the exact same issue on a Macbook Air M1 running Big Sur. I have tried uninstalling and reinstalling several times. I deleted the above mentioned folders, however some of the folders listed were not there. There are also no credentials saved in the keychain as I've never been able to get past the loading screen.
