Introduction to Microsoft Exchange 2003 Server
Exchange Server 2003 provides a reliable, extensible, and manageable infrastructure with round-the-clock email and collaboration plus low cost of ownership. MS Exchange 2003 Server supports a wide array of team functions, including group calendaring capabilities, discussion areas, and group folders, and also gives access to data that extends over geographic, logical, and technology divisions with features that include Instant Messaging, on-demand data, and video conferencing. Microsoft Exchange 2003 Server incorporated improvements over Microsoft Exchange Server 2000 in important technologies that address protection, speed, and mobility.
In 2009 Microsoft ended support for Exchange Server 2003, requiring IT managers face all the issues involved in maintaining a legacy email system. Still, many Exchange sites are currently running Microsoft Exchange 2003. Progent's Microsoft-authorized network engineers have extensive backgrounds supporting Exchange Server 2003 and can assist your business to manage and repair your current Microsoft Exchange Server 2003 solution or help you to design and carry out an affordable upgrade to an up-to-date edition of Exchange.
