What I have tried already.
1. I have tried the Exchange Remote Connectivity Analyser (https://www.testexchangeconnectivity.com/
) and everything looks fine on both my domains.
There appears to be an Exchange setting I am missing here to get these forests to see eachother on the LAN as friendly and pass messages. Any help is much apprediated.
