  3. On the contact details section, update your phone, primary email address and alternate email address. Make sure you use something different from your Office 365 email address for your alternate email address.

    Use the contact details to update admin info

    Important: The alternate email address and the mobile phone number are needed for resetting your Office 365 admin password (not your computer admin password).
