Fix Microsoft 365 Purchased Through Amazon Cannot Access Office
Question details
Users are unable to access Microsoft Office applications because their Microsoft 365 subscription purchased via Amazon is not recognized, prompting repeated sign-in requests.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to use Microsoft Office desktop applications after purchasing a Microsoft 365 subscription through Amazon.
- Observed behavior
- The Office applications suddenly stop working, fail to recognize the active subscription, and repeatedly ask the user to sign in.
Ensure you have the login credentials for your Amazon account and the Microsoft account you intend to use for your Office applications.
Activate and Link Subscription via Amazon
Manually activate the Microsoft 365 subscription from your Amazon account and link it to your Microsoft account to restore Office access.
Subscriptions purchased through Amazon often require a manual activation step to link the purchase to your Microsoft account. If this link is broken or incomplete, Office will not recognize your subscription.
Open your web browser, navigate to Amazon, and log in to the account you used to purchase Microsoft 365.
Go to 'Your Account' and select 'Your Memberships & Subscriptions' from the menu options.
Locate your Microsoft 365 subscription in the list. Check if an 'Activate Subscription' button is available. If so, click it and follow the on-screen instructions to link it to your Microsoft account.
Navigate to office.com, sign in with the newly linked Microsoft account, and check your dashboard to ensure the subscription is shown as active. Note down any specific error messages if it fails.
Open any Microsoft Office application (like Word or Excel) on your computer and sign in using the exact same Microsoft account verified in the previous step.

Frequently Asked Questions
Why does Office keep asking me to sign in even though my Amazon subscription is paid?
This usually happens because the subscription was never formally linked from your Amazon account to your Microsoft account, or because you are currently signed into the Office apps with a different Microsoft account than the one linked.
Where can I find my Microsoft 365 product key on Amazon?
Amazon typically links Microsoft 365 subscriptions digitally to your account rather than providing a traditional 25-character product key. You can manage and activate this directly from the 'Your Memberships & Subscriptions' page on Amazon.
What if my subscription shows as active on office.com but the desktop apps still won't work?
Try signing out completely from all Office applications on your device, restarting your computer, and then signing back in with the Microsoft account that holds the active subscription. In some cases, running the Microsoft Support and Recovery Assistant can also help resolve lingering activation bugs.
