When you launch Microsoft Teams, you see a brief splash/start-up screen that says ‘Loading Microsoft Teams’ at the bottom left. It appears for a few seconds before you either see the Sign In screen, or you’re taken to the Microsoft Teams interface if you’re already signed in.
The loading screen may remain on the screen a little longer for some users than it does for others. This may be because the app is trying to connect to Microsoft’s servers, verifying your sign in information, or because your system is slow.
Fix Microsoft Teams stuck on loading
If Microsoft Teams is stuck on the loading screen for more than five minutes, you’ve likely run into a problem. The reason might be anything; your password might not be correct, the cache might be corrupt, there may be a problem with the installation, or there may be a problem with Microsoft’s servers.
It is possible you’re entering the wrong password to your Microsoft Teams account. Normally, it should timeout and allow you to enter the password again but if it doesn’t, check the password.
- Visit Microsoft Teams in your browser.
- Sign in.
- If the password is correct, quit the Microsoft Teams app on Windows 10.
- Open the app again and sign in.
Remove password and sign in again
Microsoft Teams stores the password to your account in the Windows Credentials Manager. It connects with it without problem but there are always exceptions.
- Open Control Panel.
- Go to User Accounts.
- Click Manage Windows Credentials.
- Look for anything related to Microsoft Teams.
- Expand it and click Remove.
- Quit Microsoft Teams and open it again.
- Sign in with your account.
Many of Microsoft Teams’ problems stem from a corrupted cache. Deleting it will often fix the problem. The cache is rebuilt by the app.
- Quit Microsoft Teams.
- Open File Explorer.
- Enter this in the location bar
%appdata%\Microsoft\teamsand tap Enter.
- Delete the contents of these folders;
- Local Storage
- Open Microsoft Teams and sign in.
Uninstall and reinstall Microsoft Teams
If rebuilding the Cache didn’t work, uninstalling and reinstalling the app is the next step.
- Open Control Panel.
- Go to Program>Uninstall a program.
- Select Microsoft Teams and click Uninstall.
- Delete the Microsoft Teams’ cache (see previous section).
- Download Microsoft Teams and install it again.

- Dismiss the prompt to open Microsoft Teams.
- Click the option to download the Microsoft Teams client.

Microsoft Teams rarely remains stuck on the loading screen for a long time. Usually, you will see some sort of error message. In that case, you need to troubleshoot the error message.
