Hi everyone,
I am in a process of migrating Exchange 2003 to Exchange 2010.
I am able to send from Exchange 2010 to Exchange 2003.
After creating the Routing group between, I am able to send email between both Exchange 2010 and Exchange 2003.
But problem happens when after I create this routing group within my own site, one of my regional site not able to send to my Exchange 2003 anymore. The email stuck at their HT/MBX server, using a "AD site connector" to trying send to Exchange 2003. This connector is not created manually. Regional site Exchange 2010 had a existing Routing Group with the Exchange 2003 I am having, and working fine before I create the new Routing group for my local Exchange 2003 & Exchange 2010
Is there anything I can check on?
Thanks and regards,
Low
