A side from the big changes you see in Exchange 2010, there’s a lot of small details you will find as you progress in your journey through the new Exchange 2010 Beta 1 build.
So when you are on a property page of an Exchange object in the EMC, notice the little icon in the lower left corner. As you can see it’s greyed out, but as soon as you change a value or setting it will be click-able. If will basically show you the Powershell command that were used to change the value or setting (very similar to PowerGUI for those of you who have played with this tool).
