Verify Your Subscription Status Online

Check your Microsoft account online to ensure the product key was successfully redeemed and applied to the correct account.

1
Redeem the Product Key

Navigate to setup.office.com in your web browser and follow the on-screen prompts to ensure your product key has been correctly redeemed.

2
Check Microsoft Services

Go to account.microsoft.com and sign in with your Microsoft account credentials.

3
Verify Subscription

Click on 'Services and subscriptions' to confirm that your specific Microsoft 365 product is listed and currently active.

Account Mismatch: If you do not see your subscription, you may have redeemed the key using a different Microsoft account. Check any alternate email addresses you own.

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.
