Configuring Your Device to Check Clark Email

Below is the information needed to configure a variety of email clients.

Exchange vs. IMAP

With many clients, you'll have a choice of using Exchange/ActiveSync or IMAP to connect. ITS strongly recommends Exchange because it has several advantages, including easier setup (it only requires that you provide your email address and password for set up while IMAP requires additional server information and Exchange provides direct access to all of the folders that are part of your mailbox (including the the calendar). .
