Product: Microsoft 365
Device & OS: not provided
Scenario: Redeeming a prepaid product key to activate a new or existing Microsoft 365 subscription.

Before you start

Ensure you are logged into the exact Microsoft account associated with the product key you just redeemed, and have your original purchase receipt from the retailer available.

Solution 1Recommended

Verify Your Subscription Status on Your Microsoft Account

Check if your product key was successfully applied to your account before taking further action, as the software may just need to sync with your account.

Sometimes the Microsoft Office application on your computer does not immediately recognize that a new key has been redeemed online. Verifying your account status will confirm if the key worked.

Sign in to Microsoft Services

Open your web browser and navigate to the Microsoft Account Services and Subscriptions page (https://account.microsoft.com/services).

Check Subscription Details

Sign in with the Microsoft account you used to redeem the product key. Locate your Microsoft 365 subscription in the list.

Verify Expiration Date

Check the expiration date and subscription status. If it shows as active and updated, the product key was successfully applied.

Restart the Office Application

Close any open Microsoft 365 apps on your device and reopen them to force the software to recognize your updated, paid subscription status.

Recurring Billing Prompts: During key redemption, Microsoft may ask for a credit card to enable recurring billing. If your subscription is active, you can safely turn off recurring billing in your account settings to avoid future charges.

Solution 2

Resolve Retailer Activation Issues

If your subscription does not appear active in your account, the retailer may not have properly activated the physical product key at the register.

Frequently Asked Questions

Why is Microsoft asking for a credit card when I already bought a prepaid key?

Microsoft often requires a payment method on file during activation to enable recurring billing for when your prepaid period ends. You can usually choose an option to skip this or turn off recurring billing in your account settings immediately after entering the details.

Can I get a refund if my store-bought product key doesn't work?

Refunds for store-bought product keys must be handled directly by the third-party retailer where you purchased the key. Microsoft cannot issue refunds for purchases made outside of their official store.

How do I know if my Microsoft 365 product key has already been redeemed?

If you try to enter the key at setup.office.com and receive a message stating 'This product key has already been used', you should log into your Microsoft account's Services & subscriptions page to confirm if the subscription is actively tied to your account.
