I am reinstalling Exchange 2013 on a Windows Server 2012 R2 on my domain when I ran into an error on Step 7 Installing the mailbox role so I used this article
to remove all the Exchange type accounts from my AD.
When I try to add those account back by using setup /PrepareAD /IAcceptExchangeServerLice
nseTerms, it starts the process but then the command prompt windows just closes.
From the log file, I see this error being generated "A Setup failure previously occurred while installing the HubTransportRole role. Either run Setup again for just this role, or remove the role using Control Panel."
I have a pre-existing Exchange 2007 server in the domain.
I tried re-running the Exchange 2013 setup just to see what happens and it fails because it cant find the FederatedEmail.
Any help would be appreciated.
