Office 365 is Microsoft's cloud offering that provides software and services to customers on a subscription basis.
The name “Office 365” has been used by Microsoft to refer to quite a wide variety of product and services. Office 365 can refer to:
- The Office applications that run on Windows and Mac computers, as well as mobile devices such as tablets and smartphones. These applications include Word, Excel, PowerPoint, Outlook, OneNote, and more.
- The collection of Office 365 online services that provide cloud-hosted email, communication, and collaboration features to businesses, governments, and education institutions.
Office 365 Applications
Microsoft sells Office 365 Home, Home and Student, and Personal editions for use by individuals, students, and households. This subscription offering is a departure from the old model of selling Microsoft Office as a one-time purchase. By offering Office as a subscription, Microsoft is able to deliver the latest software and features to customers at all times, instead of customers needing to pay to upgrade to newer versions of Office ever 2-3 years.
The applications that are provided inn Office 365 subscriptions include Outlook, Word, Excel, PowerPoint, OneNote, and more. The specific applications included will depend on the subscription that you have. For example, Office 365 Home and Student does not include Outlook, whereas Office 365 Home and Office 365 Personal do.
