We would like to segregate a section of our LAN. We would like to configure a Firewall to only allow access to certain ports on our Exchange 2003 so that users in this segment are able to connect with their outlook and use its full functionality.
My question is what ports are necessary for outlook to be able to function correctly??
I have found the following articles, but they are more related to what ports Exchange 2000 / 2003 use :
Any help would be appreciated.
