I recently attended a webinar on Office Editing and Google Drive given by +Eric Curts. I would highly recommend that you sign up for his webinars, by visiting the SPARCC home page. They are FREE, valuable, and I always learn something new from him.
Anyway, here is a presentation on my version of his webinar: Google Drive and Microsoft Office Can Play Nice! If you have any questions, please comment in my blog and I will do my best to help you. Thank you!
Enjoy!
