  1. Go to Office.com/setup.

    Shows the setup.office.com page where you redeem your product key
  2. Sign in with your Microsoft account, or create one if you don't have one. Be sure to remember this account so that you can install or reinstall Office later, without a product key.

    Important: If you're renewing an Microsoft 365, enter the Microsoft account that's associated with your subscription. I can't remember my Microsoft account.

  3. Enter your Office product key, without hyphens.

    Note: If your work or school gave you Microsoft 365, you won't need to redeem a product key. Your admin did it for you.
