Building, integrating, or customizing apps and workflows within Microsoft Teams using developer tools and APIs
That error code in Microsoft Teams usually indicates a sign-in or authentication issue. Since you just changed your password, here are some steps to try that might resolve it:
Sign out and restart Teams: Fully sign out of Teams, then close the app completely and reopen it. Sometimes this refreshes the connection.
Clear Teams cache:
Close Teams completely.
Navigate to the cache folder:
On Windows: `%appdata%\Microsoft\Teams`
On Mac: `~/Library/Application Support/Microsoft/Teams`
Delete the contents of the Cache folder.
Restart Teams and try to sign in again.
**Use the web version:** Try signing in to [https://teams.microsoft.com](https://teams.microsoft.com) using your new password. If this works, the problem might be with the desktop app.
- Check your credentials: Make sure you’re entering the full email address as your username along with the new password.
Update Teams: Make sure your Teams app is updated to the latest version.
Restart your device: Sometimes a simple reboot helps clear up authentication problems.
Check your organization’s account status: If your account is managed by your organization (work/school), sometimes password changes take a bit to propagate. You might want to check with your IT admin if the account is active and the password sync is complete.
