A Quick blog on how to execute an Exchange PowerShell script (.ps1 extension) from a command prompt.

A .ps1 cannot be executed from a Command prompt. to execute it one needs to use a PowerShell shell. Further if this script calls any exchange cmdlet, it would require to be executed in an Exchange Management Shell.

The following command does all three in one line. i.e. run the script from c:\script\script.ps1 ( which is an exchange script ) from a command prompt.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -psconsolefile "C:\Program Files\Microsoft\Exchange Server\V14\Bin\exshell.psc1" -file "C:\script\script.ps1"
