Solution 1Recommended

Reset OneDrive Connection

Use this solution if you are saving your documents directly to OneDrive, as a corrupted sync state can trigger false sign-in prompts.

Microsoft Word often relies on OneDrive for saving documents to the cloud. If the OneDrive desktop application is experiencing sync issues or authentication glitches, Word may mistakenly believe you are signed out.

1
Open the Run dialog

Press the Windows key + R on your keyboard to open the Run window.

2
Execute the reset command

Type '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' and press Enter. This will restart the OneDrive application.

3
Verify account connection

Once OneDrive restarts, open the OneDrive settings from your system tray, navigate to the Account tab, and ensure your Microsoft account is properly linked and actively syncing.

No Data Loss: Resetting OneDrive only refreshes the application's sync state; it does not delete any of your files or folders.

Frequently Asked Questions

Why does Word say 'Sign-in required' when I am already signed in?

This usually happens when the authentication token between Microsoft Word, OneDrive, and Microsoft's servers becomes corrupted or out of sync. Network blocks or proxy settings can also cause the application to temporarily lose sight of your login status.

Can I just save my document locally to bypass the sign-in error?

You can try navigating to File > Save As and specifically choosing 'This PC' or a local folder instead of OneDrive. However, if your Office license relies on an active subscription check, it may still prompt you to sign in before allowing any save actions.

Does resetting OneDrive delete my local files?

No. Resetting OneDrive via the run command only clears the sync cache and restarts the application. Your actual files, whether stored locally or in the cloud, remain completely safe and untouched.
