Just installed Exchange2010 on Server2008R2 in an organization that has a single Exchange2003 Server on Server2003R2.
I was able to move one test mailbox with no problems and that mailbox is working inside the organization.
But I am puzzled why I don't see the new server on the 2003 Exchange server, in Exchange System Manager | Administrative Groups | <Organization Name> | Servers
Also, I don't even know how to look for this same setting on Exchange 2010... I don't see any list of servers there at all.
The Exchange 2010 server can see all the mailboxes on the Exchange 2003 machine, so I know they're talking to each other, but I'm curious about this lack of ability to administer them the way I used to be able to administer 2 different Exchange 2003 servers from a single Exchange 2003 machine.
Any enlightenment on any of this would be greatly appreciated.
