Microsoft's Office 365 is more than a set of productivity apps. Yes it does include the full downloadable Word, Excel, PowerPoint, Outlook, OneNote, Access, and Publisher applications that run on your desktop or laptop, as well as mobile versions for tablets and phones. It is, however, more like an online subscription-based ecosystem in which you run apps, access remote data, collaborate on files, and exchange information. If you get confused trying to sort out exactly how it works and what it does, you're not alone. In this review, I've tried to sort out the answers in a way that lets you get the most out of Office 365, because there's a strong chance that Office 365 is in your future, even if you aren't using it now.
