PowerShell is a shell-based automation framework created by Microsoft that allows users to manage the internal functions of other Microsoft products, including Microsoft Online Services and Exchange Online. PowerShell uses special .NET classes called cmdlets to perform various processing actions on objects in your Active Directory or Exchange Online environments. Identity Manager can use PowerShell cmdlets to perform additional event processing by sending cmdlets to the Office 356 driver using one or more policies.
NOTE:Only policies from the Subscriber channel can run PowerShell cmdlets.
