Introduction to Microsoft Exchange Server 2003
Exchange Server 2003 delivers a reliable, extensible, and manageable platform with round-the-clock email and team support plus quick return on investment. Exchange Server 2003 enables a broad array of collaborative functions, such as group calendaring abilities, discussion areas, and group folders, and also makes available information that crosses geographic, logical, and architectural divisions with features such as Instant Messaging (IM), real-time data, and video conferencing. Microsoft Exchange 2003 Server delivered enhancements over Exchange 2K Server in important areas that address protection, speed, and remote and mobile communications.
In 2009 Microsoft terminated support for Exchange 2003 Server, making IT managers face all the issues involved in maintaining a legacy messaging system. Still, many Exchange sites are currently running Microsoft Exchange 2003. Progent's Microsoft-certified IT engineers have extensive backgrounds supporting Microsoft Exchange Server 2003 and can help your organization to administer and repair your current Microsoft Exchange Server 2003 environment or help you to design and execute an economical migration to an up-to-date version of Microsoft Exchange.
