I have an issue with my users internally not being able to resolve the public namespace internally. I use domain.local as my internal namespace and domain.com as my public namespace. However I cannot get the internal users to resolve for example mail.domain.com to my exchange server's internal IP address. The main reason I am trying to get this fixed is the introduction of a WiFi connection in house that allows my mobile users to connect and use the networks data instead of the mobile data stream. However, they cannot get their internal emails while on the WiFi connection.
Any help with this would be greatly appreciated.
