We know the most reliable way, fortunately, that is the shortest as well.
AOL email settings require the users to configure SMTP/IMAP (sometimes POP, which we do not recommend). Here the details that you need to enter to setup SMTP.
• AOL SMTP server name – smtp.aol.com.
• SMTP port – 465.
• Encryption method – TLS/SSL.
• Username – your full AOL email address ending with @aol.com.
• Password – Your correct AOL Mail Password.
Now follow these settings to configure IMAP.
• Server name – imap.aol.com
• Port number – 993.
• Encryption technique – SSL.
The rest of the details are common with SMTP settings.
