Greetings,
I am migrating from Exchange 2003 to Exchnage 2010.
My Exchange 2003 environment has multiple routing groups.
All internet bound mail from all 2003 routing groups flows through an SMTP connector at our central routing group (lets call it NYC) (ie. only one routing group, NYC, is allowed to route mail directly to
the internet, all outbound mail from any other routing group must route mail to the NYC routing group first then out)
Our exchange 2010 environment has a bidirectional routing group connector between the Ex2010 routing group and NYC (the one with the smtp connector)
Our Exchange 2010 enviroment also had it's own send connectors and routes mail to the internet over them.
What I am looking to do is force internet bound email from one of our routing groups (lets call it Chicago)through the ex2010 routing group and not the NYC routing group. All other 2003 routing groups should continue to send outbound e-mail through the central 2003 routing group.
To accomplish this I created a uni-directional connector from Chicago to my ex2010 RG and set the cost to 1. I then raised the cost of the RGC between Chicago and NYC to 20. I then sent an internet bound email from Chicago, but instead of going through ex2010 it went to another routing group and then to NYC and out even though the cost of this would be higher than 1 and didn't go through ex2010 at all.
Can someone tell me what this setup didn't work? I can provide further details if inecessary.
I also experienced an unexpected side effect, inbound mail for ex2010 recipients started to flow through Chicago instead of the Ex2010-NYC bidirectional connector.
