6. Restart Microsoft Teams and log in again.

This method resolves the error tag 657rx in most cases.

2. Reset Microsoft Teams App via Windows Settings

3. Click the three-dot menu > Advanced Options.
4. Scroll down and click Reset.

This will wipe the app’s internal settings and force it to reinitialize without deleting your messages or Teams channels.

4. Close the Teams app completely.
5. Reopen it and log in again with your Microsoft account.

4. Click Remove next to each one.

If the error still persists, a complete reinstall of Teams ensures any corrupted or outdated files are removed.

1. Press Windows + I to open Settings.
2. Go to Apps > Installed Apps.

3. Try signing in again.

If Teams weren’t allowed to access certain folders or network settings, this might solve the issue.

1. Temporarily disconnect from any active VPN or proxy.
2. Go to Settings > Network & Internet > Proxy.
3. Turn off Use a proxy server, if it’s enabled.
