Lastnight I implemented 2 Exchange 2010 servers each hosting both CAS and Hub Transport Roles on each. I have 2 backend Mailbox servers to implement this evening and all Ex2010 servers will coexist with a single Exchange 2003 server.
I have prepared AD/Schema/Domain, all completed successfully
All Exchange 2010 servers are on Server 2012 boxes, fully updated, hot fixes, and Filter Packs installed, plus all required Features/Roles Enabled
Certificate installed across the Ex platform
CAS & HT roles installed successfully on both 2012 servers (via command line, not GUI)
When I run EMC on one of the new HubCas servers I can see all of the Ex2003 connectors and domain settings, I can also see all of the Mailboxes & Groups.
I got the nightshift to ping emails inbound/outbound to my external mailbox and were received with seconds, and successfully replied to them all.
However, How do I know that the Exchange 2003 Mail Flow is going through the 2 new HubCas servers, and not just passing mail is it was before the new server implementation?
