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.

    Tried absolutely everything on every forum I could find and could not get around this issue.

    Then someone tried to login into Microsoft Store and got exactly the same message.

    In the end I rang MS and held until I spoke to a support guy who ran through various tests for some time before concluding that my Windows Updates had somehow missed doing a major update some time ago but had carried on doing updates until there was something critical that it needed but there was no way to roll back at that point.

    We tried various things and ended up clean installing Windows (10 N Pro) and now everything works fine. Bit of a pain creating new profiles for everyone who uses this PC + manually coping files from Window.old but everything else now works properly (and I have Office 365 and Teams apps installed on my local desktop).

    So overall happy.

    for me it helped to login with a non existing username/email. Then I got another popup window asking for username again, this time I put the correct one and needed to provide my pwd too. then Teams did start correctly again.

    Buenos días.

    Ya pude arreglar ese problema en el Teams de la empresa.

    Darle click derecho al enlace directo que abre el Teams, click en propiedades, click en compatibilidad, y ponerle en compatibilidad Windows 8....ahí si puede entrar normalmente. Sigo a la espera que Microsoft pueda arreglar ello en un futuro parche. Saludos.

    I get this same issue with every 365 app (I can use the web based versions for each but they often miss functionality of the main apps).

    It seems to be some kind of issue getting through to or response from the online microsoft login service (as its after checking the username but before asking for the pw).

    I am a little disappointed with the response from Microsoft on this one as its their desktop O/S, their Office 365 and their online logon service. It's clearly not just an one off issue with one user.

    I expect more from MS tbh.
