Exchange 2003, released near the end of 2002 has established itself as a very reliable email server for companies of all sizes. In its two main versions of Standard (also included with SBS 2003/2003 R2) and Enterprise, it has provided email support for many years. This section of the web site provides articles and guidance on using this version of Exchange.
Many of the articles will also apply to Exchange 2000, but this is not stated individually. If you are still using Exchange 2000, and things on this site don't match exactly, then it is most likely something that wasn't available in that version.
