Solution 1Recommended

Verify Your Microsoft Account and Subscription Status

Checking your account status resolves the issue if you are signed out, using the wrong account, or if your subscription payment failed.

The most common cause of the 'Unlicensed Product' error is being signed into the Office application with an email address that doesn't have an active Microsoft 365 subscription or Office license.

Check the signed-in account

Open any Office application such as Word. Click on 'File' in the top-left corner, then select 'Account' at the bottom of the left menu. Look under 'User Information' to see which account is currently logged in.

Sign in with the correct account

If the wrong account is displayed, click 'Sign out'. Then, click 'Sign in' and enter the credentials for the Microsoft account associated with your Office purchase.

Verify subscription online

Open a web browser and go to the Microsoft Services & subscriptions page. Log in to confirm that your Microsoft 365 subscription is active and that there are no pending payment issues.

Verify Your Microsoft Account and Subscription Status

Restart Required: After signing in with the correct account or updating your payment method, close all Office applications completely and reopen them to refresh the license status.

Solution 2

Use the Microsoft Support and Recovery Assistant

If verifying your account doesn't work, Microsoft provides an automated tool to diagnose and fix activation errors.

Frequently Asked Questions

Can I still view my files if Microsoft Office says it is unlicensed?

Yes. When Microsoft Office becomes unlicensed, it enters 'Reduced Functionality Mode'. You will still be able to open, view, and print your documents, but all editing features and the ability to create new documents will be disabled.

Why did my Microsoft Office suddenly become an unlicensed product?

This typically occurs if your Microsoft 365 subscription recently expired, a recurring payment failed, or if your device has been offline for longer than 30 days, preventing Microsoft from verifying your active license.

Does reinstalling Office fix the unlicensed product error?

Reinstalling usually does not resolve this error because the issue is tied to your Microsoft account's license status rather than the software files. You should verify your subscription status online and check your signed-in account before attempting a full reinstallation.
