This is an excellent book for anyone (developer or user) who needs to learn the full benefits of your Office365 subscription.
I just migrated a client of 30 users from hosted exchange to Office365. This is the book I gave to the chief of operations when he asked “what was so great about Office365?” Within a few hours he was running team sites and some basic workflows.
It’s a tremendous reference with many step-by-step guides and in-depth details.
For developers, this is a great introduction on Office365 development. In addition, it give a good overview of how to write custom code to interact with your Office365 applications.
