Solution 1Recommended

Verify Account Subscription Status and Re-sign In

Refresh your application's login state to force Microsoft Office to recognize your recently renewed subscription.

Often, Office applications fail to sync automatically with Microsoft's activation servers immediately after a renewal. Signing out and signing back in forces a manual refresh of your license status.

1
Check Subscription Online

Open a web browser, go to the Microsoft account portal, and sign in. Navigate to the 'Services & Subscriptions' tab to confirm your Microsoft 365 subscription is listed as active.

2
Sign Out of Office

Open any Office application like Word or Excel. Click on 'File' > 'Account' (or 'Office Account'), and click the 'Sign out' button.

3
Restart the Application

Close all open Microsoft Office applications completely to ensure the session ends.

4
Sign Back In

Reopen Word or Excel. You will be prompted to sign in. Enter the exact Microsoft account credentials associated with your active subscription.

Verify Account Subscription Status and Re-sign In
Sync Complete: Once signed back in with the correct account, the 'Product is not activated' banner should disappear immediately.

Frequently Asked Questions

Why does Word say my product is not activated after I just renewed it?

It can sometimes take a few hours for the Microsoft servers to sync your renewal status with your installed applications. Alternatively, you might be signed into Word with a different Microsoft account than the one used to purchase the renewal.

How do I know if I have Microsoft 365 Home or Business?

You can check by logging into your Microsoft account online and navigating to the 'Services & Subscriptions' page. It will list the exact name of your active plan. Your purchase receipt email will also state the specific version.

Can I still edit my documents if Microsoft 365 is not activated?

If Microsoft 365 remains unactivated for an extended period, the applications will eventually enter reduced functionality mode. You will be able to view and print documents, but you will not be able to edit them or create new ones until the software is successfully activated.
