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.

    I had same issue with Team hanging on loading screen.

    I quit Teams.

    I deleted this folder

    ~/Library/Application Support/Microsoft/Teams

    Then started teams and signed on with a different account.

    That failed with a message and then I tried to sign in with the original account and it worked.

    I tried all previous steps, none worked.

    However this did.

    Remove the Microsfoft Teams folder as previously mentioned and delete the app.

    Re-install app so that it asks you to log in:

    Do not use the account that it hangs with, I logged in with my personal account instead of my work one and it got passed the loading hang screen.  I then signed out and signed back in with the original work account i was having the hang with.  It then got passed the hanging loading screen.

    So what I would suggest is try a different account (create another MS one if you do not have another)

    Then revert to original.

    Note: You will have to delete the folders in library as previously mentioned and reinstall app, otherwise it will not present you with the account login before the hanging loading window.

    Hope this helps

    The issue is clearly linked to the Big Sur update. After that, I couldnt use mute, or any of the buttons, I could type messages in meetings but in some cases couldnt see who was in meetings, if I reloaded I could see who was in the meeting but couldnt get involved in the meeting. 

    Basically We are now waiting for Microsoft to update its side so it works with Big Sur. Its my own fault for jumping the gun and updating straight away instead of waiting for every other organsation to play catch up.

    Yes, the above solution worked perfectly. Thanks CFS!

    There is definitely a programming flaw in MS Teams application for Big Sur update however you may bypass this issue by simply following the above mentioned steps which is :

    Step1 - Open any previous our upcoming TEAMS meeting invite from your calendar or emails.

    Step 2 - The pop-up will prompt you to open the TEAMS application - allow.

    Step 3 - It will prompt you to sign-in if you are the meeting organiser

    Step 4 - Sign-in with your login credentials 

    Step 5 - The pop-up will prompt for your permission to allow Camera and Microphone access.

    Step 6 - You are all set.

    Happy Teaming!

    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.
