Introducing Exchange Server 2003
Microsoft Exchange 2003 Server provides a dependable, extensible, and manageable infrastructure with 24◊7 messaging and collaboration plus quick return on investment. MS Exchange Server 2003 enables a wide array of collaborative activities, including group calendaring abilities, discussion areas, and group folders, and also makes available data that extends over territorial, organizational, and technology barriers with features that include Instant Messaging, on-demand information, and video conferencing.

This makes Exchange Server 2003 less expensive to administer and maintain and in addition allows better protection.
