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:

The ports are pretty well documented, as you have to set static ports for use with a load balancer. That process is outlined here:

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).

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)
