In the Release Notes there is a section which reads, "Windows PowerShellThe latest version of Windows PowerShell must be installed because the Exchange Management Console runs inside / on top of Windows PowerShell.".I think this is incorrect.Exchange 2007 Beta 2 uses Monad RC0. The latest version of Windows PowerShell is RC1 which, I suspect, won't work correctly with Exchange 2007 Beta 2. For example, Exchange still uses .msh file extension. The PowerShell RC1 uses .ps1.Andrew Watt MVP

Good catch, yes you are right that beta 2 requires Monad RC0---good thing about this doc bug is though... if we don't change the text it will be correct at RTM :)
