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.

    I have multiple users experiencing the same thing. Error code 0xCAA30194; Most can use the web version but the desktop app is "failing to connect". I have trouble tickets coming in left and right over the past few days. I followed these instructions, removed and reinstalled, cleared ccmcache. I am at a loss.

    I'm also facing the same problem almost for last two months. Our IT admin head also failed to resolve this issue.

    • Right click MS Teams app icon and open the 'Properties' window.
    • Under 'Compatibility' tab, check the 'Run this program in compatibility mode for:' and select Windows 8
    • Click Apply and Click OK.

    This helps to resolved my teams issue. :)

    Hope this can help you too.

    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.

    Same problem to me... tried everyting.... chache cleared, json file removed, reinstalled many times... nothing worked :(

    Alessandro,

    I found that enabling TLS 1.0 / 1.1 and 1.2 in Internet Options has fixed this for me. 

    I turned off 1.0 and 1.1 for something else a while ago. Turns out you kind of need these onfor Microsoft Teams.

    I hope this works for you man!

    Kind Regards,

    Jeff

    Hi，Shawn！

    Thanks for your quick reply.

    I have already tried the instructions you mentioned above, however, unfortunately the error persists.

    I'd like to try send error log to you if possible. 

    Regards!

    Dahai
