How you activate Office depends on whether you have a Microsoft 365 subscription or a one-time purchase of Office.

Microsoft 365 subscription

If you have a Microsoft 365 subscription, you won’t need a product key to activate. Instead you’ll sign in with the email address that’s associated with Office.

  1. In the Get Started wizard, click Sign in to an existing Microsoft 365 subscription.

    Tip: If the wizard isn’t open, start an Office application and click Activate Now.
