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 Mary, 

    I had a similar issue and was able to solve it in the System Preferences. 

    • System Preferences>Security & Privacy
    • Click on the Privacy Tab
    • On the left scroll bar find and click on Accessibility
    • You will need to click on the padlock and enter your admin credentials
    • Make sure Microsoft Teams is there and checked

    I hope this helps you. 

    Best of luck,

    Joe

    I had the same issue on a new Macbook Pro 16" Big Sur 11.1 all of the various suggestions failed for me.

    Just for clarity - the symptoms were - opening Teams showed the splash screen but would not get any further than this.

    Having raised a support ticket with Microsoft, all of the ideas suggested did not work either, BUT I did notice that the previous download on the MS website was 93.1MB and the latest one is 97MB - obviously an update to the app.

    Completely removed the old version (I used Clean My Mac as I use this anyway) and installed this latest file (97MB) and Teams loaded correctly without error.

    It certainly feels as though MS has resolved the issue with the latest download.

    I hope this helps point some of you to a resolution like me.

    Ah, something new to try. I'll do it -- maybe it will help me too, although I'm able to get into teams but I can't share documents. Perhaps they have also addressed this. 

    Thanks!
