I take that everyone is familiar with the popular PowerGUI, a FREE tool that provides a graphical user interface to manage products that understands Powershell, like Exchange 2007. I highly recommend the tool if you are not familiar with it. The tool comes with a Powershell Script Editor as well, with help built-in to the product. Download PowerGUI here
PowerGUI can be used to manage Exchange 2003, 2007 & now 2010… Download the 2010 PowerPack here.
PowerPacks are extensible open source add-ons for PowerGUI Administrative Console. Once you import them into the console, you get rich user interface to manage the particular product.
