Hi to everyone
I need to jam together two domains: abc.com and 123.com.
abc.com has a working Exchange 2007 installation, and I'm going to install a new Exchange 2010 server into 123.com domain.
At the end, what I need to have is domain 123.com acting as Exchange resource forest and abc.com as account resource forest. So I need to create new Linked mailbox in the Exchange 2010 server and mantain accounts in the original domain.
I need some hints on which is the best way to do that, and have some doubts:
What happens to mailflow between the two Exchange servers (and incoming mails) and calendar/contacts infos during coexistence?
What I need to be care of to make everything going smooth (send connectors, which server must be the "entry point" for external mailflow...)?
Many thanks
