From an earlier install on a server that was removed it left the Arbitration mailbox though I thought it had been properly removed. How do I repair it and get it pointed back to the new server?

First, try running Setup.com /PrepareAD again. Also, try this article. I'm not sure but the technique may work for all of them. http://technet.microsoft.com/en-us/library/gg588318.aspx Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

It failed saying it needed to be restarted to complete a previous setup. I deleted the disabled SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} and the FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 I have 1 disabled system mailbox shown below, I cannot determine where it belongs. Could it be from the 2003 Exchange server or is it orphaned from the 2010 server?

ED, perhaps you can explain why I cannot recreate the federatedemail mailbox? Is it supposed to have one?
