Starting a couple weeks ago Teams on my desktop stopped opening.  It will start, you get the splash screen and then the message about login.  At that point the application exits.  You do not actually get the login prompt just a message in the splash screen. 

 

I have tried to uninstall and reinstall to get the same behavior.  I have looked at the desktop log  and don't see any errors.  It seems to show success.

 

What is happening?  How do I resolve?

Could you try to logout from the back ground process in the system tray?
Highlighted

I do not see any Teams process in the system tray nor so I seen any Teams processes in Task Manager.  When I try to start it appears briefly in Task Manage as Update.exe and in the System Tray but both go away when it fails.

So you don't have the following:

Do you have any major errors in the event logs?

Highlighted
No I do not have the system tray icon shown after it exits. I appears briefly while loading the disappears. I don’t see any log errors.

Hi @Marshall Curtis,

 

I've had a look through my logs and it looks like the app tries to access something like this:

 

https://teams.microsoft.com/desktopclient/update/1.1.00.2251/windows/x64?ring=general

 

So could you try accessing Teams through the browser via this url: https://teams.microsoft.com

 

I wonder if something is simply blocking the app.

 

Highlighted
Yes, I can access team.microsoft.com. I tried to open Teams app again with this open and the same behavior. At least this is a workaround that I hadn't thought of, since this isn't my primary machine this is helpful. I still can't figure out what is going happening. It has been working fine for some time and then it just stopped. It doesn't appear to correlate to any updates. etc.

I would suspect ports on fire walls, but then if it works for other machines then that is unlikely.

@Marshall Curtis I realize that this was posted many months ago, but I was unable to find the answer anywhere else, so I thought I'd add a working resolution here.

 

Mine started bombing out at the login screen after it forced me to log out. Right before the forced logout, I had logged into my onedrive account on the same machine using the microsoft authenticator.

 

To fix this issue, I had to delete my configuration files (i just deleted everything in here, but it's probably not necessary) from %appdata%\Microsoft\Teams and then restart Teams. You'll have to manually restore any customized settings, but it should get you running again.
