Outlook (Exchange 2010) Client TCP Ports
Trying to locate the exact set of ports Outlook (2007/2010/2013) clients locate to connect to Exchange 2010. Found this list via Microsoft but the table seems too exhaustive to lock down to a set:

Not on another network but on another virtual LAN. The document shows about three different ranges, is there anything else missing?
RPC port range is changed to 6005-59530
TCP End Point Mapper (TCP/135)
Dynamic RPC port range (49152-65535)

However if you aren't using a load balancer then you shouldn't have firewalls between the Outlook clients and Exchange. If the clients are on another network then use Outlook Anywhere (Which puts everything over 443).
