Here's some tips for finding out more about your Exchange server:
- Neil Hobson has a great tip on the MSExchange blog today about finding out the Exchange version of a server by checking a file.
- Neil also posted this tip last month about using Exchange System Manager to see more details about the servers in your organization - version, type (front-end, cluster, basic) and edition (standard, enterprise, eval).
- Another related resource is a KB article I updated a while back that has all of the major releases of Exchange, their version numbers and release dates (note to self: add Exchange 2003).
- You can also telnet to the protocol ports (such as 110 for POP3, 143 for IMAP4) to see the version of that service. Note that telnetting to SMTP (25) will tell you the version of Windows, not Exchange - but it's a quick way to tell if a server is running Win2k or Win2k3
