Clear Caches and Reconnect Work or School Account

Resolve sign-in and authentication glitches by refreshing your account connection in Windows settings.

Open Windows Account Settings

Press Windows Key + I to open Settings. Navigate to 'Accounts' and click on 'Access work or school' in the left pane.

Disconnect the account

Locate the problematic business or school account from the list, click on it, and select 'Disconnect'. Follow the on-screen prompts to remove the local credentials.

Reconnect and restart

Click 'Connect' on the same settings page to add your work or school account back. Restart your computer to clear any lingering memory caches.

Sign in to OneDrive

Launch the OneDrive desktop application and sign in with your email and password. The application should now sync without displaying the error code.

Frequently Asked Questions

What exactly does OneDrive Error 2147483661 mean?

This error code usually indicates a breakdown in the authentication process when your computer tries to connect a work or school account to Microsoft's identity servers.

Will I lose my files if I disconnect my work account in Windows settings?

No. Disconnecting the account from Windows settings only removes the local authentication token from your PC. Your files remain safely stored in the cloud and will be accessible once you reconnect.

What should I do if I cannot log into OneDrive on the web either?

If web access also fails, the issue is likely on the server side or with your specific account status. You should contact your organization's IT support team to verify if your account is locked or disabled.

How do I clear the local Microsoft identity cache manually?

While disconnecting the account in Settings is the safest method, advanced users can clear the cache by opening the Registry Editor and carefully removing the associated identity keys under HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities.
