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).
- Go to the Microsoft 365 Admin tab and select Email Aliases.
- Select the trash button next to the email alias you want to delete.
- Select Delete. After the email alias is deleted, it can be used in a new email address.
