Exchange 2003 Server provides a nearly identical implementation of the older Microsoft Outlook graphical user interface that features scheduling and utilities. As a result, mobile workers get the advantage of complete, secure availability of email even if they don't have a laptop. All they need is an Internet-connected computer with a conventional browser.
  • Unlike MS Exchange 5.5 Server, which incorporates its own directory, Microsoft Exchange 2003 Server takes advantage of Active Directory (AD), representing a more streamlined administration and security structure. This makes Exchange Server 2003 simpler to administer and support and in addition offers tighter security.
  • Exchange 2003 Server has a powerful foundation for transparently integrating third-party utilities such as virus and spam scanning tools. Microsoft Exchange 2003 Server's versatile API solves the technical risk associated with Microsoft Exchange 5.5 Server when adding third-party software.

  • Exchange Server 2003 offers powerful groupware features that allow work groups to maximize productivity by sharing scheduling, address groups, messages, and data.
  • The versatility of Exchange 2003 Server allows you to integrate non-Microsoft security add-ins or accommodate wireless computers such as the RIM BlackBerry.
