Sometimes you need to change the domain associated with your address. Before you can change your domain, it must:
- Be registered with GoDaddy.
- Be registered in the same account as your Office 365 email plan.
- Have an active zone file for the GoDaddy domain and be in the same account as your Office 365 email plan.

To continue to send and receive email, you'll need to remove your old email address from your devices and add your new one. After you remove your old email account you can Set up my Office 365 email on my phone and desktop.
- 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.
