Microsoft Office 365 is a subscription service that combines familiar Microsoft Desktop Apps available on your own computer (Word, PowerPoint, Excel, Outlook, OneNote and Publisher) with a set of web-enabled tools (Lync web conference, Exchange email for business, and additional online storage with OneDrive). It also features Office on Demand, which streams live versions of these familiar productivity tools directly to any computer with Internet access so that you can work with all of the Microsoft Apps and tools from any location and on any device. With Office 365, you also benefit from automatic upgrades and patches, so your business is always working with the latest versions of software.
