I am trying something out and am not sure if it is even possible. I have Exchange 2003 Enterprise Edition SP1 on Windows Server Enterprise Edition SP1 (dedicated). I am Tired of our company's ISP "loosing" many of our e-mails. But not all of our employees (particularly our Network Engineer) are using MS Outlook 2003 as their e-mail client. Anyways, I want to turn our exchange server into a POP3/SMTP server for our employees to use with their choice on an e-mail client. Please let me know if you have any more questions that could help with this experiment.
