Microsoft Office owner: Microsoft owns Office, now sold as Microsoft 365

Who owns Microsoft Office? Microsoft does, and the suite is sold as Microsoft 365. Here is who owns Microsoft, how Office was renamed and what the Copilot app is.

Microsoft owns Microsoft Office. The suite, which includes Word, Excel and PowerPoint, is made and sold by Microsoft and is now marketed under the Microsoft 365 name. The Microsoft Office owner is therefore Microsoft, and Microsoft itself is owned by public shareholders, with Vanguard (7.48%) and BlackRock (7.30%) the largest, according to its 2026 proxy statement. 12

Microsoft Office owner: who owns Office?

People who search “Microsoft office owner” are usually asking one of two things: which company owns Office, and who owns that company. The first answer is Microsoft. The second is its shareholders, because Microsoft is a Nasdaq-listed company with no single owner. We break that down in our report on who is the owner of Microsoft. 2

Key facts

Item Detail
Owner of Office Microsoft Corporation
Core apps Word, Excel, PowerPoint
Subscription name Microsoft 365
Office hub app, November 2022 Renamed Microsoft 365 app
Office hub app, 15 January 2025 Renamed Microsoft 365 Copilot app
Chairman and CEO Satya Nadella

Did Microsoft rename Office?

Not the apps themselves. Microsoft told Windows Central that Word, Excel and PowerPoint are unchanged. In November 2022 it renamed only the Office hub app, used on the web and mobile, to the Microsoft 365 app, and in January 2025 it renamed that hub again to the Microsoft 365 Copilot app. 3

The confusion grew because office.com now sends visitors to the Copilot hub, which made some reports claim the Office brand had been dropped. Microsoft denied that, Windows Latest reported in January 2026, and Office Watch reached the same conclusion. 45

Who runs the company that owns Office?

Satya Nadella is chairman and CEO of Microsoft, having led it since February 2014. Microsoft was started in 1975 by Bill Gates and Paul Allen, who no longer control it. Read our guide to the Microsoft founders and the Microsoft company page. 2

What happens next

Expect more Copilot branding across Microsoft’s apps. Microsoft says the Office apps and the Microsoft 365 subscription stay in place, so the owner of Office remains Microsoft whatever the hub app is called. 34
