Hi Team,
Recently setup Exch 2013 envirionment with CU5, having two CAS (On Hyper-V2012R2) and four MBX servers(DAG)(On Hyper-V2008R2), all on seperate VMs.
This is in Co-existence with Ex 2010 sp3. I followed the following KB for CAS13 configuration:
http://technet.microsoft.com/en-us/library/jj218640(v=exchg.150).aspx
But I am unable send\receive mail internally from 2013 users to 2010 and vice versa. Mails are released from the outboxes from both types of users but never reached the destination.
Both CAS servers are fully internet-facing but since I am concerned with internal mail flow only, internet doesnt matter.
Any clue\help or KB, would be higly appreciated.
Thank You.
