I came across two new Office 2010 related guides at the Microsoft Download Center this past week that may be of interest to you.
The first one is the Operations Guide for Microsoft Office 2010:
This book provides information about how to maintain and manage your installation after you have deployed Microsoft Office 2010. The audience for this book includes IT generalists, IT operations, help desk and deployment staff, IT messaging administrators, and consultants.
The content in this book is a copy of selected content in the Office 2010 technical library (http://go.microsoft.com/fwlink/?LinkId=181453) as of the publication date. For the most current content, see the technical library on the Web.
The second one is called Deploying Office 2010 at Microsoft:
Microsoft IT (MSIT) developed a testing and deployment strategy to deliver Office 2010 to more than 100,000 desktop computers at Microsoft. The testing strategy resulted in a robust product that has been rigorously tested in a production environment. Learn about the best practices that MSIT developed, the deployment tools that MSIT used, how MSIT tested Line of Business applications, and the key communications and training that MSIT created for the Microsoft user community.
