All of a sudden I Can’t send or receive mail. Every message says something I need CHANGE “IMAP settings
They’re using an alternative email. It’s got my wrong Email Address/Apple ID. How
do I put it back? They don’t have my password. What’s an IMAP setting? How do I set it back? (Help!)
Please delete and re-add your account. Please check the Incoming mail server settings in your email application, and make sure they match the IMAP/POP settings in the section titled “AOL Mail POP and IMAP settings” from the following help article: https://help.aol.com/articles/how-do-i-use-other-email-applications-to-send-and-receive-my-aol-mail
The incoming and outgoing mail servers require SSL enabled for all ports, and also the username field in the account setup, needs to contain your full email address, including @aol.com at the end.
In case your server settings are correct, open the link below (and sign in if necessary), and make sure the option “Allow apps that use less secure sign-in” is turned ON.

After this turning ON this option, check if your mail application is able to connect. If the problem persists, verify if the “Two-step verification” option on the Account Security page (the URL above) is turned ON or OFF.
In case this feature is turned ON, you will have to create a unique application-specific password for each one of your email applications, by following the steps from the section titled “How do I set up 2-step verification?” from the following article: https://help.aol.com/articles/2-step-verification-stronger-than-your-password-alone
