Investigate Billing and Verify Your Subscription Online
Log into your Microsoft account via a web browser to confirm your purchase and force the license registration from the backend.
Often, the local application fails to sync with Microsoft's servers. Verifying your purchase history online can prompt the system to register the license properly.
Open a web browser, navigate to the Microsoft account services website, and sign in using the exact account used to purchase Microsoft 365.
Navigate to the 'Services & subscriptions' or 'Payment & billing' section of your account dashboard.
Locate your Microsoft 365 purchase in the transaction list and select 'Investigate billing' or 'Manage'.
Submit a request for review if the license is not active. Microsoft will verify the payment, register the license, or notify you if a refund or another resolution is needed.

Re-authenticate Your Account in Office Applications
Sign out and sign back into the local Office application to refresh your cached account credentials.

Frequently Asked Questions
Why does Microsoft 365 say it is unlicensed despite being installed?
This usually happens if the application isn't signed in with the correct purchasing account, your subscription has expired, or there is a synchronization error between the local app and Microsoft's billing servers.
Can I use Microsoft 365 if it is not registered?
Unregistered or unlicensed Microsoft 365 applications will eventually enter reduced functionality mode. You will only be able to view and print documents, but not edit or create new ones.
How long does it take for a new Microsoft 365 subscription to activate?
Typically, a new subscription activates immediately after purchase. However, during high server traffic or payment processing delays, it may take up to 24 hours for the license to fully register to your account.
