Where is my account page?
Go to Office.com and click My Account. If you’re prompted to, sign in with the email address and password you used to set up Office. If you can’t remember which email address you used, contact support. Need help signing in? See Sign in to Office.
If you’re installing for first time, you might not have an account page yet. You’ll set that up as a part of installing Office.
