Microsoft Office 365 ProPlus - Online Installer 3.3.17

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.
The suite currently includes a word processor (Word), a spreadsheet program (Excel), a presentation program (PowerPoint), a note-taking program (OneNote), and an email client (Outlook); the Windows version also includes a database management system (Access).
