Hi,

One of our users keep getting an error message when opening teams, this is only happening to a single users, on their machine, unfortunately I am not able to check if it would work on other machine or if other users can work on their machine due to working from home. Basically it opens, asks them to login, when they login it doesn't ask for password it just goes straight to the error, and we can't get further, they are able to login to teams.microsoft.com, but the app wont work, I have tried the following steps:

Reinstalled the app

Rebooted the machine

Uninstalled the app, cleared the cache and then reinstalled the app

Closed the app and cleared the cache and then reopened the app

Removed the teams license from o365 admin portal, then re-added the teams license

is there anything else I can do to try to resolve this issue? 

Kind Regards,

Brendan

    Hi All

     Thank you for help. I tried the following:

     1. Proxy dis-able when not using the same

     2. Compatibility thread.

     Neither of which helped. I checked with my local support, they mentioned possible cause could be due to mis-match of Domain password and Office365 password. For me to resolve this i need to visit my office and re-set my domain controller password to be same as Office365 password.

     In the meantime, I am using the following steps:

     1. Log-in to windows without home network

     2. Connect to home network

     3. Login into teams using Chrome browser.

    Regards

    Buenas tardes

    Tenía el mismo inconveniente y lo solucioné!!

    Luego de intentar desinstalarlo e instalarlo de nuevo seguía y seguía el inconveniente, e hice ajustes a la cuenta del usuario y aún seguía molestando, después de varias veces insistir hice el siguiente procedimiento para no tener que formatear el equipo:

    1. desinstalación de Microsoft Teams
    2. Ir a Editor de registro: Tecla Windows + R Luego escribir regedit, Enter y buscar la ruta en la ventana que se abre (HKEY_CURRENT_USER\SOFTWARE\Microsoft) buscar la carpeta de Teams y eliminarla.
    3. Hacer lo mismo en: ( HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft), verificar que quede eliminada o no esté la carpeta en esas 2 rutas, si está, eliminarla!
    4. Eliminación de temporales: Tecla Windows + R Luego escribir temp, eliminar todos los datos que nos permita, los que no solamente dar en omitir, hacer el mismo procedimiento en %temp% y en prefetch.
    5. reiniciar el ordenador.
    6. volver a instalar Microsoft Teams preferiblemente desde office.com loggeando con una cuenta de Microsoft, sino sencillamente buscarlo en el navegador.

    A mi me funcionó haciendo exactamente ese procedimiento en 2 equipos diferentes, no tocar las cuentas ya que el inconveniente es por registros del ordenador!

    Espero les sirva mi respuesta para la solución.

    Saludos desde Colombia!

    We only solved it after releasing the IP for full output to the internet, without rules. But after we reactivated the rules, Teams remained connected normally.

    My colleague is facing same situation. What is the "rule" in your posting? I wanna know how can I operate to release the IP what you mentioned.
