Can ping my email server (xyx.domain.com) from the outside but not inside the network.

I can only ping my email server (MS Exchange on 2003) domain (xyz.domain.com) only if I'm outside my network. I can ping the internal IP just fine. This has got to be a simple DNS setting but I'm not sure. I get spun around in circles when figuring out forward and reverse zones with this setup and don't want to bring down my Exchange server by trying to fix this annoyance.

Until now, it has only been an annoyance because all is working. The trouble begins when it comes to Android Sync setups. The domain name is entered and it won't work if the Android is connected to the house WiFi. Disconnect from house WiFI and use 3G/4G, it works fine! Now my CFO has a new tablet that runs off Android OS and would like to be able to use the Sync feature inside or outside the network.

Help!

In DNS make sure a host (A) record exists for xyz.domain.com then create an mx record for xyz.domain.com just for consistency. i'm guessing your internal domain is the same as the external domain.com  instead of domain.local or something else.

if your internal domain is different from the external domain, you will have to create a new primary dns zone and copy all public dns records to the internal zone, using internal ip address of the xyz.domain.com record  

don't forget to run ipconfig /flushdns from a command line before testing to make sure its not getting a cached address.
