Sample chapters from Powershell book
A good friend of mine, Ilse Van Criekinge (Exchange MVP and winner of this year's Speaker Idol at TechEd IT Forum) is the author of a Powershell book that will be released very soon.
The book, Exchange Management Shell: TFM, is not ready yet, but the good news is that you can already download some unedited sample chapters for free from the SAPIEN site.
Feedback is appreciated and can be e-mailed to errata@sapien.com or directly to Ilse: ilse.vancriekinge@pro-exchange.be.
"Exchange Management Shell: TFM provides the answers in a "cookbook" format that focuses on real-world Exchange Server 2007 management tasks, and how to accomplish them in Windows PowerShell. This authoritative and comprehensive book includes a standardized "crash course" in Windows PowerShell for newcomers, and dives right into the nuts and bolts of becoming a leading-edge, command-line Exchange administrator."
