I'm trying to load Exchange Management Shell and it gives me a big 'ol red error that says:

Import-Module : There were errors in loading the format data file: Microsoft.PowerShell, , %APPDATA%\Roaming\Microsoft\Exchange\RemotePowerShell\DOMAINNAME.format.ps1xml :

File skipped because of the following validation exception: File %APPDATA%\Roaming\Microsoft\Exchange\RemotePowerShell\DOMAINNAME.format.ps1xml cannot be loaded.

The file %APPDATA%\Roaming\Microsoft\ExchangeRemotePowerShell\DOMAINNAME\DOMAINNAME.format.ps1xml is not digitally signed. The script will not execute on the system. Please see "get-help about_signing" for more details...

The %APPDATA% is stored on an external server on my network (that I can ping to without problems). I am missing a ton of PS cmdlets too, which I'm presuming are stored in '*.format.ps1xml'

I tried finding the directory in which format.ps1xml is supposed to reside on the external server and it's not even created.

Can someone tell me where to start?
