I have been using the Powershell more and more as I go about configuring Send and Recieve connectors, Unified Messaging and one annoying aspect is knowing what parameters and variables you can use.
Sure, you can type the Get-ExCommand but it doesn't WordWrap so you only see a proportion of the commands, which I personally find incredibly annoying..! But here's the solution:
[MSH] Get-excommand |format-table -wrap
It will cetainly prove VERY useful..!
