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 :)

Hi!

There is a string with several possible causes and fixes here

https://techcommunity.microsoft.com/t5/Microsoft-Teams/Blank-screen-when-opening-Teams-app-on-window...

Could be one of these. If they don’t work then I would recommend raising a support case with Microsoft.

To note, one of the solutions was changing the username so you may want to try this. It is recommended to generally avoid using special characters such as # in usernames where possible.

Hope that answers your question!

Best, Chris

Hi,
Did you get the answer?
One more question, is your user profile located in different location/path than the default one under C:\Users ?

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."
