Frequently Asked Questions

Why does Excel say my product is deactivated?

This usually occurs if your Microsoft 365 subscription has expired, a recurring payment failed, or Excel is struggling to connect to Microsoft's licensing servers due to a corrupted cached credential.

Is it safe to delete the Office Identity registry key?

Yes, deleting the Identity key is a standard troubleshooting step for Office activation issues. However, you should always back up the registry first. Office will automatically recreate the necessary keys the next time you sign in.

Will clearing the OneAuth and IdentityCache folders delete my files?

No, clearing these folders only removes temporary authentication data used by Office applications. Your personal spreadsheets and documents remain completely safe and untouched on your device.
