Connectiong to Internal Exchange server from Lan using External MX Record
-
Im having problems connecting to my Internal Exchange Server from inside the lan Using my External MX address.. First when i try and access the WebMail it just goes to the pfsense web gui.. chaning the port does not fix this issue.. also Cell phones can no longer connect because they are pointing to the external mail.server.com record and all seems to be stoping at the pfsense box…
Everything works fine from outside the LAN..
Help :)

Look around the forums for something called nat reflection. Also you can create a dns zone to handle the translation.
Are your cell phones are using an internal wifi network to connect to the server?Usually they use the cell network to get on the internet, and If they're using the cell network to get on the internet, they should have an IP from the cell providor and be able to type in the external address of the email server.
To access owa internally, use https:\servername\exchange (or https:\servername\owa if using 2007 or 2010) or setup a dns zone in your DC to translate.

Check your port forwards and make sure their "external address" is set to your WAN address, and not "Any".
That can cause problems if you have NAT reflection enabled, and will do almost exactly what you describe.
