Enable and Disable Exchange Features
Exchange features provide added functionality for your mailbox-enabled and mail-enabled users. For example, the Exchange feature Instant Messaging provides your users with the ability to know when their coworkers or friends are online. Your users can then communicate by sending an instant message to one or several of their coworkers or friends at once.
