It sounds like your routing-group-connector isn't bi-directional. Open the Exchange Management Shell, enter "get-routinggroupconnector" and make sure both sides are correct.

I recently installed Exchange 2007. I forgot to suppress the Link State and now have done so. I can send mail from a user on Exchange 2007 to the internet and to a user on 2003. I can't send mail from Exchange 2003 to 2007? Can someone help me with this? Help?
