Microsoft Office 365 is a suite of cloud-based productivity and collaboration applications that includes the latest versions of Microsoft Office, Exchange Online, SharePoint Online, Skype for Business, and other services. It is designed to help businesses and individuals stay connected and productive from anywhere, on any device.
Microsoft Office, MS Office, or simply Office, is an office suite and (formerly) a family of client software, server software, and services developed by Microsoft. The first version of the Office suite, announced by Bill Gates on August 1, 1988, at COMDEX, contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint, all three of which remain core products in Office. Over time, the Office suite has grown substantially, adding programs such as OneNote and Outlook; the suite has also been made highly extensible with the use of the VBA scripting language.
