AOL Mail is the name for AOL's free e-mail service. You can delete your AOL e-mail account at any time by cancelling your free AOL account. Deleting your AOL account, however, will permanently remove all of your sent and received e-mails from AOL's servers. You cannot recover a deleted AOL e-mail account or recover any of the associated e-mail messages.
Go to the AOL My Account home page (See Resources).
Enter your AOL e-mail address and password and click the "Sign In" button.
Enter the answer to your AOL security question. You set up your AOL security question at the time you created your AOL account. Click the "Continue" button.
Click the "Manage My Subscriptions" option.
Click the "Cancel" link located at the bottom-right corner of the AOL window.
Select the reason you want to cancel your free AOL Mail account from the drop-down menu.
Click the "Cancel AOL" button to complete the cancellation process and permanently delete your free AOL Mail account.
Deleting your free AOL Mail account will also result in the closure of any additional free AOL services associated with your AOL mail account such as your AIM instant messenger account. It is not possible to close your free AOL Mail account without also closing your associated free AOL services.
