Exchange 2010 setup problems - FederatedEmail account missing
Posted on 2013-12-29
Trying to install Exchange 2010 on Windows 2012.
Installation of Hub Transport role fails as FederatedEmail account is missing.
However, running setup.com /PrepareAD also fails as follows:
"Setup encountered a problem while validating the state of Active Directory: The Active Directory organization configuration version (15763) is higher than Setup's version (14322). Therefor, PrepareAD can't be executed."
This box is to replace an existing SBS 2008 machine with Exchange 2007. So it is also a domain controller and the forestprep has been run in order to add it as a domain controller.
How can I reinstate the FederatedEmail account ?
