If your AOL Email Not Receiving Emails, you can solve it by doing the following. To ensure that your messages are properly organized, you may need to double-check any filters you've created. Make sure Block All Senders Except Contacts is unchecked under mail settings --> block senders. If this option is enabled, you will not receive messages from people who are not in your contacts list. If possible, request that the sender resend the message to see if you can receive it again.
