It turns out that my TechEd Exchange Scripting with PowerShell session was recorded to video, and now it's available for all to download (no more having to provide TechEd credentials!). Link below on the session title to the video of my session and to the rest of the sessions they've just released!
Microsoft Windows PowerShell Scripting for Microsoft Exchange Server 2007
Evan Dodds, Program Manager, Microsoft Corporation
This session covers the new Windows PowerShell-based Exchange cmdline and scripting interface. Learn how to convert your multiple page Visual Basic and COM scripts to mere one-liners in Exchange 2007. We cover the basics of the management shell, as well as the underlying design and key concepts. Additionally, we go into more depth on how to build larger scripts that can be used to automate small, medium, as well as enterprise business scenarios.
