I have been getting errors when trying to send from a user in my E2K3 <> E2K7 Exchange Org. The problem seems to be related to sharing a namespace between the two organizations.
My setting is below.
Internet > E2K3 > SMTP Connector > E2K7.
My Exchage 2K3 is authoritative for company.com and non authoritative in E2K7.
From what I have been reading, I need to make the shared namespace non authoritatve in both Exchange organizations. Can someone please confirm this? One article I read shows that this can be overcome by using the SMTP Virtual server "Forward all mail with unresolved recipients to host" setting.
If it helps in answering these questions, I will be using Galsync to create contacts for users in the other forest,
When I try and send an email from old domain to a user in the new domain, I get the following error:
Below is the error I was getting.

A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.
