Delete my Office 365 email alias
If you’re no longer interested in using an email alias, you can delete it from the Email & Office dashboard. After you’ve deleted an email alias, you can create a different email address with that same name.
- Sign in to your Email & Office dashboard (use your GoDaddy username and password).
- Click Admin and select Email Aliases.
- Click the trash button next to the email alias you want to delete.
- Click Delete. After the email alias is deleted, it can be used in a new email address.
