When you are on the inside of the firewall you need to use the internal IP
address of the exchange server. DNS is resolving that record to an external
IP address and when you are inside the network there is no reason to go
through your firewall to connect to your exchange server which is on the
inside of your network (im assuming). And besides as you can see it doesn't
work like that.
