Nothing beats being refreshed in August, so soon after relasing Exchange 2007 Beta 2 Help, Microsoft is releasing an update. As before, this is the standalone version that you can install on any workstationor server, seeing that it is simple CHM file.
From looking at the refresh it seems like lots is still missing. Looking forward for the next version.
