Ports used by Exchange Server while communicating with MS Outlook Clients
Posted on 2009-04-20
We are running MS Exchange 2003 and using MS outlook clients that connect over RPC End point mapper (port 135) to Exchange Server. We wish to know which TCP port the exchange server uses in turn for further communication with the outlook clients.
Based on the monitoring tools, we just saw that it used tcp 1144 once but then it was changed to 1164.
The objective is to implement QoS on the routers based on the protocol type.
