How To Find Product Key for MS Office Subscription

For a Microsoft 365/Office subscription, a product key is normally not needed after initial redemption. The subscription is tied to a Microsoft account, and installation/activation is done by signing in with that account, not by reusing a key.

To move the subscription to another laptop:

1. Go to the Microsoft account Services & subscriptions page: https://account.microsoft.com/services/
2. Sign in with the Microsoft account originally used to buy or redeem the subscription.
3. Under Services & subscriptions, locate the Microsoft 365/Office subscription.
4. Use the Install option shown there to download and install Office on the new laptop.
5. When prompted during or after installation, sign in with the same Microsoft account to activate. A product key is not required.

If the subscription was originally activated with a key card, that key is now converted into an entitlement on the Microsoft account and is not needed again. If there are problems with activation or the account used is unknown, use the guidance under Microsoft 365 is prompting me for a product key and Use the right Microsoft account in the product key documentation, or contact Microsoft Support from the product key help page.
