Businesses today rely on their messaging and collaboration servers more than ever. This reliance means that you do not just need a way to send e-mail or create groupware. Businesses need a comprehensive messaging platform that includes the tools necessary to create rich collaboration applications. Microsoft Exchange Server is that platform.
