What is the name of Microsoft's cloud-based office suite?

Microsoft’s cloud-based office suite is Microsoft 365. It is a product family that combines productivity applications with online services, collaboration tools, storage, and subscription-based access.

The suite includes familiar programs such as Word, Excel, PowerPoint, OneNote, and Outlook. Depending on the plan, it can also include services such as OneDrive, Teams, SharePoint, Exchange Online, and enterprise security or device-management tools. Many applications work through web browsers as well as installed desktop and mobile versions.

The service began as Office 365. Microsoft introduced Office 365 in 2010 and made it generally available in 2011, initially emphasizing hosted business services. In 2020, Microsoft renamed most consumer and small-business Office 365 plans as Microsoft 365 to highlight the broader collection of cloud services beyond the traditional Office applications.

Microsoft 365 is commonly confused with the perpetual-license editions of Microsoft Office. A Microsoft 365 subscription generally includes ongoing feature updates and cloud benefits, while a standalone Office license is purchased for a particular version and does not provide the same subscription ecosystem.
