If you’re responsible Office 2007 training, you may be interested in Microsoft’s Office2007 training roadmaps. Each roadmap shows you what online courses are available for each Office application and what each course covers. You can use the roadmaps to map out a path to efficiently and effectively develop the necessary skills.
Furthermore, although each course is available online, you can download shorter PPT versions of some courses and use them as training material for users.
The Office 2007 training roadmaps are available here.
