Exchange Server 2003 delivers a dependable, scalable, and easy-to-manage platform offering 24×7 messaging and collaboration plus quick return on investment. Microsoft Exchange Server 2003 enables a wide range of collaborative activities, such as group scheduling capabilities, discussion areas, and team folders, and also gives access to data that crosses territorial, logical, and architectural divisions with productivity enhancers such as Instant Messaging, on-demand information, and video conferencing.

Advantages of Exchange 2003 Vs. Microsoft Exchange 5.5

This makes Microsoft Exchange Server 2003 less expensive to manage and maintain and in addition allows better security.
• MS Exchange Server 2003 has a powerful architecture for transparently integrating non-Microsoft utilities including anti-virus and anti-spamming tools. MS Exchange Server 2003's versatile Application Programming Interface (API) eliminates the instability associated with Exchange Server 5.5 when integrating third-party utilities.
