I have come down to the last (hopefully) errors in re-installing an Exchange Server 2010. There is a separate AD which is a production machine, hence my many problems since the original Exchange was not properly excised. It says (although I am in all the AD Exchange Security Groups and am an Enterprise Admin) that I do not have sufficient permission to view the Organization Configuration (yet am the one who both set up the original and the redo). I do not have outlook on the server machine. I did try to wrest my way in through the Windows (not Exchange) Power Shell, but receive the following error after setting up my credential: PS C:\Windows\system32> Import-PSSession $Session -AllowClobber Import-Module : There were errors in loading the format data file: Microsoft.Exchange.Management.PowerShell.Setup, C:\Program Files\Microsoft\Exchange Server\V14\bin\Exchange.format. ps1xml : File skipped because it was already present from "Microsoft.Exchange.Management.PowerShell.E2010". At line:3 char:30 + Import-Module <<<< -Name $name -Alias * -Function * -Prefix $prefix -DisableNameChecking -PassThru -ArgumentList @($session) + CategoryInfo : InvalidOperation: (:) [Import-Module], RuntimeException + FullyQualifiedErrorId : FormatXmlUpateException,Microsoft.PowerShell.Commands.ImportModuleCommand I have been trying to resolve this (and all the other errors) for over two weeks. If this cannot be resolved today, I believe I will quit and wipe the server machine clean, set it up in its own domain and institute a two way trust between my domain and it - that will at least work (I hope).
