Error code - caa30194

There's a more permanent way to sign in to Microsoft Teams. If you're having trouble completing the process, talk to your IT admin"

Our company has been using Teams  for a while, it works very well for me until today. I can't sign in Teams desktop in my computer after I upgraded my OS from Win7 to Win10. But the funny part is that Teams web and Teams in my Phone(android)  are still working very well. The desktop Teams feedbacks with error code: 0xCAA30194, which is attached below. Can anyone help with it? Thanks in advance.

    Same for me - working for all my colleagues - working for me on company terminal server but as soon as I sign in on my local machine (which I need to do to have effective mic audio during meetings) I get the 404 error followed by the error code.

    I am getting this after entering my username (either my own personal or company one) and clicking next - before it even asks for a password?

    I have tried everything here - surely some at MS must have done some proper investigation into this issue rather than just telling us to clear the cache?

    How do I upload my log.txt file (do I send it via PM)?

    Hi kjewell23!

    Not sure if it will work for you, but i resolved my issue by disabling antivirus. 

    So for now, I am not using Teams on desktop till I have time to figure out how to run Teams with antivirus enabled.

    Uninstalled Teams, deleted all Teams folders from %appdata%, removed all Teams references in the registry, restarted and reinstalled with AV off and still exactly the same.

    Tried logging in with my personal 365 account and with my work one and just the same after entering username (email address) and clicking next, get th 404 message (ie before it even asks for password).

    I can log in to webapp version of Teams or any other Office app but try and use the desktop version and I get this issue (the Teams one is simpler, less information but still 404)
