Office 365 combines the familiar Microsoft Office desktop suite with cloud-based versions of Microsoft's communications and collaboration services—including Microsoft Exchange Online, Microsoft SharePoint Online, and Microsoft Office Web Apps.

SharePoint is a web application platform in the Microsoft Office server suite. Launched in 2001, SharePoint combines various functions which are traditionally separate applications: intranet, extranet, content management, document management, personal cloud, enterprise social networking, enterprise search, business intelligence, workflow management, web content management, and an enterprise application store. SharePoint servers have traditionally been deployed for internal use in mid-size businesses and large departments alongside Microsoft Exchange, Skype for Business, and Office Web Application Server; but Microsoft's 'Office 365' software as a service offering (which includes a version of SharePoint) has led to increased usage of SharePoint in smaller organizations.
