Office 365 account identification

Question

I don't remember which account I used to subscribe to Office 365.

Answer 1

For a Microsoft 365 (Office 365) subscription for home, the account used is the same email address that was used when the subscription was first bought or activated, and the same one used to sign in to install or manage Microsoft 365 from the account portal.

If that account email cannot be remembered, use the guidance in the “I forgot the account I use with Microsoft 365” article for Microsoft 365 for home products. It explains how to identify which Microsoft account is associated with the subscription and how to recover access so the subscription and installations can be managed.

If Office was installed but the account is unknown, the “Troubleshoot installing Office” article for Office for home points to the same recovery steps under “You forgot the account you associated with Office.”
