- Device & OS
- not provided
- Scenario
- The user wants to remove promotional advertisements from their Office applications after purchasing a valid software license.
- Observed behavior
- Advertisements continue to appear in Word, Excel, and PowerPoint because the software is either not properly activated, signed into the wrong account, or mismatched with the installed version.
Ensure you have the exact Microsoft account credentials used to redeem your product key and a stable internet connection to communicate with Microsoft's activation servers.
Verify Your Subscription Status Online
Check your Microsoft account online to ensure the product key was successfully redeemed and applied to the correct account.
Often, product keys are redeemed but fail to sync with your desktop applications. Verifying your subscription online confirms that your purchase is active and linked to the right email address.
Navigate to setup.office.com in your web browser and follow the on-screen prompts to ensure your product key has been correctly redeemed.
Go to account.microsoft.com and sign in with your Microsoft account credentials.
Click on 'Services and subscriptions' to confirm that your specific Microsoft 365 product is listed and currently active.

Refresh Activation Status in Office Apps
Force the Office applications to recognize your newly redeemed license directly from the software interface.
Contact Third-Party Retailers (e.g., Amazon)
If you purchased your license through a third-party retailer, activation and billing must often be managed through their specific platforms.

Frequently Asked Questions
Why does Word still say 'Unlicensed Product' after I entered my key?
This usually happens if your Office application is signed into a different Microsoft account than the one you used to redeem the product key. Open File > Account, sign out, and sign back in with the correct email address.
Can I hide the upgrade advertisements in free Office versions?
If your subscription has expired or you are using the free web versions of Microsoft Office, promotional advertisements are built into the interface. They can only be permanently removed by activating a valid premium desktop license.
What should I do if my Amazon-purchased Microsoft 365 key doesn't work?
Because third-party retailers handle transactions on their end, you must contact Amazon customer support directly for billing, cancellation, or replacement assistance regarding digital software purchases.
