Hi, my Teams Desktop App doesn't start - I always get a white GUI.
The problem is the SSO. My userid for Windows includes a #. So I think the App gets an error with this special sign. I would lik to force the app to bring the sign in GUI, but I didn't find anything.
Do you have an idea how to force the desktop app to go to the sign in window an to stop the SSO?
APP version is 1.2.00.1758
Thanks a lot :)

I FIXED IT!!! I have been banging my head on this for what seems like forever and then I found this.
"Close out of teams completely. On Windows 10, in your search menu, search Email & Accounts. I noticed that the people that had the issue had their windows accounts missing here. I clicked Add a work or school account under the accounts used by other apps section. Then had them log in.
Teams would immediately log in without the issue. I tried logging out and restarting the PC and had them log back in and it stayed fix. Doing more testing but seems promising for me so far."

I too encountered the dreaded blank/white Teams logon dialogue. Canceling out gave me error code - 4c7. If I let it time out after five minutes I got error code caa7000a.
My fix: Uninstall Teams, delete everything in Credential Manager, then delete Teams folders from the user's profile. Reboot, then re-install teams. The folders I deleted were:

In the end I managed to solve my problem more simply. I had tried quitting and restarting Teams several times, but always got back to the white login dialog - sometimes it faded as though busy and unresponsive. However, the Teams main window was there in the background - I found that I could click on the profile icon and select "Sign out". Teams shut down. Next time I started, I was able to sign in successfully.
