Microsoft 365 from GoDaddy Help

Change the domain on my Microsoft 365 email account

If you purchased a new domain that reflects your brand, you might want to update your email account to match. But before you can change the domain associated with your Microsoft 365 account, it must:

  • Be registered in the same account as your Microsoft 365 email plan.
  • Have its DNS registered in the same account as your Microsoft 365 email plan.
  • Not be set up on an existing Microsoft 365 organization.
Note: If you want to use a domain that's not registered with GoDaddy or uses external DNS, contact our GoDaddy Guides. After we link the domain name so it's part of your Microsoft 365 organization, you can follow the steps below.

  • If you change the username, it automatically creates an alias (or a forward) of the previous username so you won't miss any emails sent to the old email address.
