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 had the same issue and this fix the problem for me.

    Upon looking deeper into the Teams log, it was noticed that the runtime failure was causing because of the file not found errors related to all 4 JSON files in the Teams installable location below. Though the json files were exist on that location but I assume that they may have got corrupted. I have deleted all 4 json files along with logs file from this location and restart the Teams, sign in and BOOM!!. All the 4 Json files and a log file has been re-created and no issues logging into Teams since then😊

    Buenos días.

    Yo hace unas dos semanas que tengo el mismo error al usar el teams versión escritorio de una pc de la empresa.

    Ya hice todos los pasos indicados, incluso seguí los pasos de un usuario que comentaba borrar los archivos json, pero nada, sigue el mismo error.

    Para comentar que la versión web si funciona normal.

    Agradecería su ayuda por favor.

    Atte.

    I have this problem too.

    Sometimes, when i reinstall the application, i can use it again.

    Now even that won't work anymore.

    I deleted the cache and all the other files inside the folders mentioned above.

    My company is using Teams as main platform to communicate and the webversion is not cutting it for me.

    Kind regards.

    Jeff
