Our current production environment is one Exchange 2007 - Version 8.3 (Build 83.6) running Hub Transport, Client Access, Mailbox roles. There's also a orphaned Exchange 2007 that was never used, it was virtual and got deleted without being uninstalled.
I have inherited the task of moving existing to Exchange 2010, and have 2 servers located at 2 physical sites connected via mpls circuit, same AD domain and forest. I have managed to get both servers running: Exchange Server 2010 SP2 -188.8.131.52 however one failed and the Mailbox role did not install, so need assistance getting that done assuming it's needed for a DAG, the goal being if one site server goes down were still up and running, also want Outlook Anywhere working.
It's not a large install, about 100 mailboxes but as can be expected, critical to the business. Thank you.
