After attending Harold's Technet Event in Phoenix area, I realized that I can install Exchange 2007 Management Tools on my Vista box.
I already had Powershell for Vista installed, so that was not a problem. Exchange GUI setup Wizard allowed me to run Setup. However, it came back as an error. You have to install two features for Management Tools. You need IIS6 Management Console and IIS Metabase and IIS6 Configuration compatiblity.
Go to Control Panels -> Programs and Features. Then, select "Turn on Features on or off".Select these features:
Click Ok. Let the Features install.
Then, Install Management Tools as usual.
