Dell running XP Pro over cable internet connection using Outlook 2003. POP3 / STMP -- new installation of Outlook, new computer and upon setting up Outlook account for first use got the error message "Task '<mailserver> - Sending' reported error (0x80042109) : 'Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP)"
Computer new out of box and same with Outlook....went to Microsoft knowledge base and followed their recomondations - didn't fix problem. Could it be Port setting (25)?
