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 the same issue and it solved the problem for me. Also check sharing settings within the System Settings and be sure that Teams is allowed.  Hope this helps!

    Thank you for this idea -- tried this, and per Graham, downloaded the latest upgrade for Teams (which allows me now to use a background -- one problem solved!), but I still can't share documents. I made a little progress because instead of a black strip where the screen share options should be, I'm getting the little circling arrow showing me it is looking for something. But it never finds it...

    I've changed privacy settings in Accessibility and given access to EVERYTHING on my computer (not that happy with doing this, but thought it might be the ticket).

    So annoying, because I'm an independent consultant and have to use THIS platform to deliver training to one of my clients.

    Maybe they'll eventually find the bug that keeping it from work on Big Sur and on my (brand new) Macbook Pro.

    Ugh.

    But again, thanks.

    .: I just installed MS Teams on my 2020 MacBook Pro. I am using macOS Big Sur v11.1.

    When I open the app and login, it takes me immediately to a screen that looks like this:

    Image

    When I click on "Sign up for Teams," it takes me back to the web, where it takes me back to the above page, except this time on the web, not the app.

    At the bottom of that screen, it reads: "Already signed up? Check your email for a link to start using Microsoft Teams." No email was subsequently received.

    I don't know what else to try at this point. It's like I'm in an infinite loop.

    Anyone else experiencing this?

    SOLVED

    If you are getting the constant crashes and restart loops of the Teams app once you’ve logged in with MacOS Big Sur and the blank window after 4-5 seconds,

    I can confirm that Joe.Price308ad's answer on Page 2 of this forum WORKED.

    n fact, I just purchased a Macbook Pro 2020 with Big Sur (Fresh installation) and the symptoms were the same as described here. After having tried everything from clearing the cache to uninstalling and combination of the 2 above, I finally tried the following and it worked!

    Here is the excerpt with the added step you would need to do to make it work.

    1. Close Microsoft Teams (or Force Quit (Option + Right-Click or Option +Contextual Menu) if it is in a constant restarting loop)

    On your Mac OS, under the Apple logo, go to:

    • 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
    • IF MICROSOFT TEAMS is not in there, Add it by clicking on the + button, navigate to your Applications folder (go all the way back and you will see your Applications folder, then Select Microsoft Teams).
    • It should now be added to the list and should be Checked.
    • Close the System Preferences window.
    • Restart Microsoft Teams

    Thanks Joe and Good Luck All!

    Hi All,

    I tried this fix (several times) when it was first suggested. Unfortunately, it does not work for me.  When I try to share, I just get a spinning arrow in the black band at the bottom of the video box. It never finds anything to share.

    Could there be something else I have set differently????

    Thanks to those who have been trying to help. I really appreciate it. 

    Best,

    Mary
