Teams is not opening on macbook

Anonymous

Hello,

I have a user that uses a MacBook pro with Catalina on it. Recently teams have not been wanting to work on this user's computer. There were times where it was opened, but then froze and bogged down the performance of the MacBook. Sometimes it wouldn't open when the user would log into their computer for the day. It would just bounce and never open or give out an error.

We have uninstalled and reinstalled the program to his computer but now it just bounces like it is opening but then never does open. I have looked at other solutions like deleting the ~/Library/Caches/com.microsoft.teams and teams folder but again the same issue.

This MacBook is about 1 month old and has the current update and the rest of the Microsoft office programs work fine on there. The user is currently using the web version of the teams to get by for now. Wondering if there is anything we can try to get this working again.
Thank you

Ok guys I am running Big Sur. What I had to do was as follow

Open up you calendar and find a teams meeting.
Once you click on the meeting like your going to join. It will pop up a message asking if you want to use the desktop app.
It will then ask you to login and once you do that it works.

Hi Phil

Please keep in mind that Nathan does not work for Microsoft nor can he speak for the company any more than you or I. The audience of this forum is fellow users. Only if you see MSFT under someone's name does that person work for Microsoft.

Thanks for the answer Nathan but Microsoft, how is this the accepted answer?

If I were to release software to my clients that required this kind of action when it's started I would be out of customers and out of business quickly.

Fix your software.

This actually did the trick for me on MacOS 10.15.7 Catalina
Ran through the full uninstall process, rebooted and reinstalled Teams, rebooted again for good measure.

Then set myself a Calendar entry with a Teams meeting in Outlook and joined from there. And all of a sudden, the application loads and is back to normal.

Thanks for the tipp! Saved the rest of my working week and more I guess.

Steps that worked for me, based on your tip. I'm running MacOS 11 if that helps anyone
1. Closed out of the Teams App
2. Opened up a calendar item with a teams meeting
3. Selected to join the meeting
4. In the meeting, it will ask you to sign in for a better experience
5. Select to sign in (do not join the meeting)
6. after signing in, close out of teams
7. Open teams backup and log in again
8. NOTE: if you are connected as a guest to multiple teams like I am, you will get a prompt to select an organization to open.
9. All is well in my world now
One more note. I had this issue after performing a fresh installation of MacOS 11 due to a flickering display issue. Fresh install of my Office apps too. I point this out because if Teams never opens properly, you never find the folders everyone is talking about to delete.

Hope this additional information to the original suggestion helps someone.
