Hello!

I have recently been experiencing some issues when trying to access the desktop app of Teams on a Windows 10 system. I downloaded the latest installer from the Teams website, and when I attempt to log in, the following message appears: "Personal accounts aren't supported yet in Teams (Preview)." However, when I perform the same process on a desktop with Windows 11, it works perfectly.

I have tried several solutions to resolve the issue with the desktop app, including:

  • Clearing the cache;
  • Reinstalling the app;
  • Formatting some machines;
  • Using the offline mass installation version of the app.

As expected, none of these solutions worked, except for using Teams on the web.

Note: I asked some of my friends to try downloading the desktop app on their machines, and every single one of them encountered the same result. Therefore, it is likely that this issue is affecting everyone trying to download and log in. Some of them already had the app installed and were logged in, and it worked fine for them until they logged out to assist me in testing the app.

Thank you for your attention.

Try these steps

First, close and uninstall Teams via Windows settings > Apps.

Log in to the web version, then select "Meet" to generate a meeting link.

Paste the meeting link into a new browser tab and open it; once you see the "Join your Teams meeting" screen, look for the "Download now" option at the bottom and install the application.

After installation, the option to join the meeting will appear immediately; look for the "Sign in" option at the bottom, log in with your account, see if it lets you.
