Summary

Microsoft Exchange Server 2007 continues to build on a solid history of messaging servers. Improvements in the architecture of Exchange 2007 allow for continued innovation, improvement, and scalability. The move to the 64-bit architecture is clearly needed to allow Exchange to be enhanced further and to reduce I/O requirements.

Server installation and configuration has been further enhanced and simplified by the introduction of server roles; the person that performs the Exchange Server installation chooses, which components are necessary for a particular server's function.
