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 can confirm that deleting the Application Support/Microsoft/Teams and com.microsoft.teams folders in combination with logging into a personal account and then switching to the work account works.

    It was not necessary for me to delete the folders in between the switch, just upfront. (didnt test to not delete them)

    I have a MacBookPro 2019 with BigSur and latest teams from the website (today, now downloaded).

    Possible workaround: Use the Microsoft Teams web version. It works faster, more smoothly and isn't affected by MacOS Big Sur!

    Just to reiterate, the latest version of the Teams app works with Big Sur. I have installed on a number of Mac’s with no issues. 

    the web version is one answer but because of the feature gap between the web and desktop client, its worth perservering in my opinion.

    .: 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:

    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?

    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.

    Graham
