I am fairly desperate on this and would appreciate any help. Here is the setup.
Parent domain: abc.com
Child domain: xyz.abd.com
Mailserver FQDN in Parent Domain: server1.abc.com
Mailserver FQDN in Child domain: server2.xyz.abc.com
The process used was as follows:
Child DC server setup and DCPrmo'd. ForestPRep run on DC's in both Parent & Child. Domainprep ther same. Exchange installed, Exchange SP2 installed. Connector configured.
I am able to create new users with email addresses in the child domain, can access information from the parent domain and vice versa.
The problem is that every time I send an email from a user in the parent domain to a user in the child domain, I get the following error:
The following recipient(s) cannot be reached:

Thanks in advance.
