Windows TCP/UDP Ports
A good friend of mine, Todd, sent me a link to this document:
Service overview and network port requirements for the Windows Server system
The first section of the article contains a list of the Windows Server and client services with their corresponding TCP/UDP port numbers, sorted by the service itself. The Exchange Server and Outlook clients section is quite comprehensive, with related articles regarding the use of static ports and information about RPC over HTTP.
The second part of the article contains a summary table sorted by port number to make it easy to identify which services listen on a particular port.
A valuable article.
