A customer recently asked us whether the Group Policy Overview for Office 2007 downloadable book was available for Office 2010. The answer is "Not Yet," but in the meantime I've assembled the following list of Office 2010 Resource Kit articles that cover Group Policy.

I'll be working on creating the Group Policy downloadable book for Office 2010 in the coming weeks. You can find a current list of our Office 2010 downloadable Resource Kit content on TechNet. Let us know if there is a collection of Resource Kit content that you like to see made available as downloadable books.
