POP3 & IMAP Configurations

What is POP3 and IMAP?

E-mail clients, such as Eudora, Outlook Express, Netscape Mail, Pine, etc., cannot access MS Exchange via the default protocol (MAPI) created by Microsoft. Instead, they must access e-mail via POP3 or IMAP. POP3 and IMAP access is extremely limited.

It just allows for the receiving and sending of e-mail. Your data will not be kept on the server, and therefore you cannot access your full mailbox from anywhere; you will also not be able to share your calendar, folders, Public Folders, Global Address List, etc.

To setup a POP3 or IMAP client:

Exchange 2007

Incoming Server Name:


Outgoing Server Name (SMTP):


Username or Account name:



Your Email Password

Port Settings:

Incoming Port (no SSL): 143

Outgoing Port (no SSL): 25 or 587

Incoming Port (SSL): 993

Outgoing Port (SSL): 465 then select TLS
