Email, Exchange, IMAP Email Access to Exchange

This page contains information about how to connect to the Technology Services Exchange email and calendar service using the IMAP protocol, which is used by some mobile devices and email clients.

Limitations of IMAP

The configuration given below uses the IMAP email protocol rather than the Exchange protocol. This means that many email clients which don't have full Exchange or ActiveSync support can probably connect to the Exchange server using IMAP instead.

Note that IMAP only provides an email connection. You won't receive calendar information through IMAP.

IMAP account settings

Due to the number of different IMAP email clients, it's not possible to provide a menu-by-menu and screen-by-screen set of instructions for configurations. However, once you locate your email client's configuration section, these are the settings you will use.
