FAQs

Most Common Cause of Returned Mail

Believe it or not, the most common reason for a returned email is because the recipient's email address was incorrect. An email address must be typed correctly with no spaces and with the @ symbol in the correct place, for example, user name@aol.com.

User Unknown

The unknown user message means either the username doesn't exist on the AOL® service or no longer exists on the AOL service.

Mailbox Full

Another reason for a returned email could be that the recipient's mailbox is full.

Is Not Accepting Mail From This Sender

The recipient may have blocked email from your email address.

Delivery Not Authorized
