Auto configuration in Evolution doesn't work for AOL at the moment. There was change on AOL side around 7.11.2017 and port 993/995 should be used for imap/pop secure connection. Auto configuration provided by api.gnome.org still contain old information (port 143/110):

   </incomingServer>
    <incomingServer type="imap">
      <hostname>imap.aol.com</hostname>
      <port>143</port>
      <socketType>STARTTLS</socketType>
      <username>%EMAILLOCALPART%</username>
      <authentication>password-cleartext</authentication>
    </incomingServer>

    </incomingServer>
    <incomingServer type="pop3">
      <hostname>pop.aol.com</hostname>
      <port>110</port>
      <socketType>STARTTLS</socketType>

      <authentication>password-cleartext</authentication>
    </incomingServer>

I did a test with Mozilla Thunderbird and auto configuration worked, so I compared data used by Thunderbird, they don't use 143/110 anymore.

Could you please update data provided by api.gnome.org for aol.com and aim.com domains?
I know that auto configuration is not part of Evolution anymore, but couldn't figure out which section in bugzilla should be used.
