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.

    Hi Dahai He,

    Thanks for reaching us in community!

    For such an issue, you can first try to clear Teams cache in your PC to see if it helps for your dilemma:

    1. Fully exit the Microsoft Teams desktop client.
    2. Go to File Explorer, and type in %appdata%\Microsoft\teams.
    3. Once in the directory, you’ll see a few of the following folders:

    a. From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.

       *   %appdata%\Microsoft\teams\application cache\cache

    b. From within ‘Blob_storage’, delete any files that are located in here if any.

       *   %appdata%\Microsoft\teams\blob_storage

    c. From within ‘Cache’, delete all files.

       *   %appdata%\Microsoft\teams\Cache

    d. From within ‘databases’, delete all files.

       *   %appdata%\Microsoft\teams\databases

    e. From within ‘GPUCache’, delete all files.

       *   %appdata%\Microsoft\teams\GPUcache

    f. From within ‘IndexedDB’, delete the .db file.

       *   %appdata%\Microsoft\teams\IndexedDB

    g. From within ‘Local Storage’, delete all files.

       *   %appdata%\Microsoft\teams\Local Storage

    h. Lastly, from within ‘tmp’, delete any file.

       *   %appdata%\Microsoft\teams\tmp

    1. Restart Teams client.

    If clearing cache cannot resolve your problem, we'd like check the error log from you so that we can analyze your situation further. I will generate a private message for you, please kindly check the email notification later.

    Best,

    Shawn

    in my case this was helpful. If you are using AD FS, you have to set ADFS properties to support Edge Chromium. However I don't have SSO running so I have to type login credentials.

    AD FS on Windows 2016 and later:

    Set-AdfsProperties -WIASupportedUserAgents @("MSIE 6.0", "MSIE 7.0; Windows NT", "MSIE 8.0", "MSIE 9.0", "MSIE 10.0; Windows NT 6", "Windows NT 6.3; Trident/7.0", "Windows NT 6.3; Win64; x64; Trident/7.0", "Windows NT 6.3; WOW64; Trident/7.0", "Windows NT 6.2; Trident/7.0", "Windows NT 6.2; Win64; x64; Trident/7.0", "Windows NT 6.2; WOW64; Trident/7.0", "Windows NT 6.1; Trident/7.0", "Windows NT 6.1; Win64; x64; Trident/7.0", "Windows NT 6.1; WOW64; Trident/7.0", "MSIPC", "Windows Rights Management Client", "Edg/*")

    AD FS on Windows 2012 and earlier:

    Set-AdfsProperties -WIASupportedUserAgents @("MSIE 6.0", "MSIE 7.0; Windows NT", "MSIE 8.0", "MSIE 9.0", "MSIE 10.0; Windows NT 6", "Windows NT 6.3; Trident/7.0", "Windows NT 6.3; Win64; x64; Trident/7.0", "Windows NT 6.3; WOW64; Trident/7.0", "Windows NT 6.2; Trident/7.0", "Windows NT 6.2; Win64; x64; Trident/7.0", "Windows NT 6.2; WOW64; Trident/7.0", "Windows NT 6.1; Trident/7.0", "Windows NT 6.1; Win64; x64; Trident/7.0", "Windows NT 6.1; WOW64; Trident/7.0", "MSIPC", "Windows Rights Management Client", "Edg/79.0.309.43")

    More in this article:

    Hope this helps I was stuck hours in checking SSO and AD FS.
