Vasu Jain, a Windows Desktop Experience MVP from India, has authored an eBook which is a compilation of one of the finest tips and tricks about Microsoft Office 2010.
The book is divided into seven sections. Section one covers Office 2010 features as a whole while sections 2 – 5 cover features in Word, Excel, PowerPoint and Outlook respectively. Section 6 includes some additional utilities for Office 2010, and section 7 would dive into Office Web apps and Office Mobile Apps. Spread over 250 pages, containing over 60 articles, the eBook helps you to enrich and enhance your experience with Microsoft Office 2010.
I posted a blog entry at www.homelandsecureit.com/.../microsoft-office-2010-version-features-and-suggested-retail-pricing-simplified which shows the different versions of Microsoft Office 2010 and their suggested retail pricing. That may be of assistance.
