whenever I try to join a meeting this message box appears. I uninstalled and reinstalled the app. But it did not help. In the web version, I can join. I do not know what is wrong with the app.

Hola amigos:
¡Logré solucionar el problema!
1.- Primero desinstalen su Microsoft Teams desde control panel
2.- Reinicien su Equipo
3.- Apretar la tecla Windows+E en la parte superior %appdata%
4 .- Acceda a %AppData%\Microsoft\teams\ y borre las subcarpeta
5.- Finalmente instalen su Microsoft Teams de escritorio y con eso quedara resuelto.
Try updating the app. Worked for me!

@Elnur1997 managed to fix issue with driver update, specifically audio driver.

Dell - Dell official driver website


  1. Exit Microsoft Teams completely. To do that, you need to right-click the Teams icon on the taskbar and select Quit.
  2. Type %appdata%\Microsoft\Teams in the Windows Search bar and hit Enter.
  3. Delete all the files from the Teams folder.
  4. Then relaunch the app and check if the alert is gone

Hope it fixes the issue. Cheers!!!


Thanks, it work for me
