You're trying to configure Outlook 2000 to send and receive mail through your America Online account, but none of the configuration options you choose seem to work.
As of this writing, AOL mail does not work with any Internet-standard (POP3, IMAP, or SMTP) mail client software. Although it is possible that AOL will add this support sometime in the future, at this time you must use AOL's access software to send and receive mail.
