Frequently Asked Questions

Why didn't I receive a product key for my Microsoft 365 Basic purchase?

When purchasing directly through the Microsoft Store, Microsoft 365 subscriptions are digitally linked to your Microsoft account. Because of this digital entitlement system, no 25-character product key is generated or needed.

How do I know which Microsoft account is linked to my subscription?

Search your email inboxes for a confirmation receipt from Microsoft. The email address that received the order confirmation is typically the account linked to your new Microsoft 365 subscription.

Can I manually transfer my Microsoft 365 subscription to a different email address?

You cannot manually transfer a subscription between Microsoft accounts. If you used the wrong email address during purchase, you must contact Microsoft Billing Support to help resolve the issue securely.

What should I do if my Microsoft account page says I don't have an active subscription?

Ensure you are completely signed out of any work or school accounts and signed into the exact personal Microsoft account used for the purchase. If the subscription still doesn't appear, check your bank or credit card history to ensure the transaction was successfully processed.
