Introducing Exchange 2003 Server
Exchange 2003 Server provides a dependable, scalable, and manageable infrastructure with 247 email and collaboration as well as low cost of ownership. Microsoft Exchange Server 2003 supports a wide range of collaborative functions, including group calendaring abilities, discussion areas, and team folders, and also gives access to information that crosses geographic, organizational, and technology divisions with features that include Instant Messaging (IM), on-demand data, and video conferencing.

  • Exchange Server 2003 has a strong foundation for transparently adding third-party applications including anti-virus and anti-spamming tools. Exchange Server 2003's versatile Application Programming Interface (API) eliminates the technical risk often found with Microsoft Exchange 5.5 when adding independent software.

  • Exchange Server 2003 offers an array of collaboration features that allow teams to improve efficiency by sharing scheduling, address books, correspondence, and files.
