Frequently Asked Questions

Why does my Word document say it is locked on my Mac?

This typically occurs when your Microsoft Office license has expired, is not activated, or if you are signed into the app using a Microsoft account that does not have an active subscription. The app limits functionality to read-only mode until a valid license is confirmed.

Can I edit a locked Word document without activating Office?

Yes, you can temporarily bypass local app restrictions by uploading the file to OneDrive and editing it using Word for the Web. Alternatively, you can use a free office suite like WPS Office to open and edit the .docx file directly on your Mac.

Does uninstalling and reinstalling Word fix the activation lock?

No, uninstalling and reinstalling the application typically does not resolve activation issues. The lock is tied to your account's subscription status, so you must sign in with a valid Microsoft 365 account or use a valid standalone license key to unlock editing features.
