I have a user in my office that just purchased an Iphone and would like to be able to access his e-mail from anywhere over the EDGE network. My Exchange Server is running the IMAP4 service. What steps do I need to take to get the user to be able to connect using IMAP? How do I know the name of my IMAP outgoing and incomming mail server? Do I need to do any further configuration on the server?
