Microsoft Windows PowerShell 1.0

The Exchange management tools are implemented as an extension, or snapin, of Microsoft PowerShell. Currently only PowerShell version 1.0 is supported and needs to be installed on the server:

The PowerShell environment logs messages to the event viewer. There are two event logs created for PowerShell in a standard installation: the “PowerShell” and “Windows PowerShell” event logs. The “PowerShell” event log is used when the gateway creates a PowerShell runtime environment. When a write operation fails to write to the event log, the PowerShell environment will not start up, and all PowerShell-related actions of the gateway will fail. To prevent this failure, you should monitor and clean up the event log regularly or configure it to overwrite messages.
