Exchange 2010 – EMC Error ‘GetSteppablePipeline execution of scripts is disabled’

KB ID 0001351 


Seen when attempting to open the Exchange Management Console;

EMC-error GetSteppablePipeline

Exception calling “GetSteppablePipeline: with “1” argument(s): File C:\ProgramFiles\Exchange Server\v14\RemoteScripts\ConsoleInitialize.ps1 cannot be loaded because the  execution of scripts is disabled on this system. Please see “get-help about_signing” for more details.”


This is usually caused by an update rollup, and can be easily fixed by running the following command at an administrative PowerShell session.

Set-ExecutionPolicy RemoteSigned -scope LocalMachine

Set PowerShell Execution Policy

Note: Sometimes you may get an error message;

Set-ExecutionPolicy : Access to the registry key ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell’ is denied.

If that happens launch regedit.exe navigate to the above value and change it from ‘Restricted’ to ‘Unrestricted’.
