What is Microsoft 365 (formerly Office 365)? Everything you need to know
Summary
As a product line, Microsoft Office dates back nearly three decades, with early versions essentially combining Word, Excel, and PowerPoint into a discounted bundle. Second, it combines a suite of online services, including business-class email, cloud file storage, and secure communication tools along with the traditional desktop apps. This collaborative platform replaces the older Skype for Business service, offering unified communications, HD video conferencing, and instant messaging for Microsoft 365 subscribers in an organization, along with a team-and-channel-based architecture that covers much of the same feature set as alternatives like Slack. Every Microsoft 365 plan that includes desktop apps offers the following Office applications for all supported versions of Windows and for MacOS: Outlook, Word, Excel, PowerPoint, and OneNote. When you sign in with an active subscription on mobile devices (iOS and Android) , a new unified Office app offers a single place to create, view, and edit Word, Excel, and PowerPoint files.
