Check out the Exchange Server 2007 documentation update notes for a list of topics that were updated today in our February refresh.
We also released an updated Exchange Management Shell help file. This help update brings the Exchange Management Shell help in sync with the content available on the Microsoft TechNet site and in the Exchange Server 2007 product help file.
To update the Exchange Management Shell help, download the updated help file and extract it over top of the existing Exchange Management Shell Help file, Microsoft.Exchange.Management-Help.xml. By default the help file will extract to C:\Program Files\Microsoft\Exchange Server\Bin\en. If you installed Exchange Server 2007 to a different path, or if your installation locale is not English (en), modify your path accordingly.
Once you have extracted the updated help file to the correct location, close the Exchange Management Shell and re-open it to load the updated help file.
