Reactivate Office via Account Settings

Sign in with your associated Microsoft account or enter your product key directly within the Word or Excel application.

1
Open Office Account Settings

Launch Microsoft Word or Excel, click on 'File' in the top-left menu, and select 'Account' or 'Office Account' from the left sidebar.

2
Review Product Information

Look at the 'Product Information' section on the right side of the screen to check the current activation status of your Office suite.

Activate or Change Key

Frequently Asked Questions

Why is Office asking for a product key after a BitLocker recovery?

A BitLocker recovery indicates a significant system event. This can cause Windows to refresh hardware IDs or system tokens, prompting Microsoft Office to temporarily lose its digital license verification and ask for reactivation.

How do I find my lost Microsoft Office product key?

You can typically find your product key in the original purchase confirmation email, inside the physical product box, or by logging into your Microsoft Account online and checking your digital order history.

Will I lose my Word and Excel documents if my Office activation fails?

No, your documents are safely stored on your local hard drive or cloud storage. An activation issue only restricts your ability to edit or create new files in Microsoft Office, but the files themselves remain intact and can be opened with alternative software like WPS Office.
