Security Issues - If you cancel your services, you will not be able to reset your email address on att.com. It is strongly recommended to set up security questions before canceling. This makes it easier to reset passwords if you forget them.
Merged email addresses - If your Yahoo email is linked to your att.net email, you have the option to unassign them. The att.net e-mail is deleted when you delete the account. You must process the request within 30 days of the cancellation.
