Introducing Microsoft Exchange Server 2003
Microsoft Exchange Server 2003 delivers a dependable, scalable, and manageable infrastructure with 24◊7 email and collaboration plus low cost of ownership. Exchange Server 2003 supports a broad array of collaborative functions, including group scheduling abilities, discussion groups, and team folders, and also makes available information across geographic, logical, and architectural barriers with features such as Instant Messaging (IM), real-time data, and video conferencing. Exchange Server 2003 introduced improvements over MS Exchange Server 2000 in important technologies that address security, performance, and remote access.
In 2009 Microsoft terminated support for Exchange Server 2003, making IT management face the issues associated with maintaining a legacy messaging system. Still, a large number of Exchange sites are still operating Microsoft Exchange Server 2003. Progent's Microsoft-certified network consultants have in-depth experience maintaining Microsoft Exchange 2003 and can help your business to administer and repair your existing Microsoft Exchange Server 2003 solution or assist you to design and execute an affordable upgrade to a current edition of Exchange.
