Activate Office

When you start an Microsoft 365 app that's not activated, you'll be prompted to sign in to Microsoft 365. Be sure to sign in using the Microsoft account, or work or school account, that you used to buy or subscribe to Microsoft 365.

If the Activation wizard appears, Microsoft 365 needs your help to activate. Follow the prompts in the wizard to activate Microsoft 365.

If this screen appears, Microsoft 365 is installed as a Microsoft 365 Family trial

You'll see this screen if you sign in to Microsoft 365 that was pre-installed on a new device but don't have an Microsoft 365 product associated with your account.

To use Microsoft 365 on your new device, you can activate Microsoft 365 as a 1-month trial of Microsoft 365 Family. You can also buy Microsoft 365, add Microsoft 365 to an existing Microsoft 365 subscription, or enter a product key from a new product key card. If you have an older copy of Microsoft 365, you can install that instead.
