Microsoft’s New ‘One Outlook’ App Leaks Online

Microsoft is testing a new Outlook app that will replace the built-in Mail and Calendar apps on Windows 10. Codenamed Monarch and “One Outlook,” the app is “a new version of Outlook designed for big-screen experiences,” according to a leaked version of the app.

While the leaked app isn’t functional without a full internal Microsoft account, the One Outlook app replaces desktop versions (win32 and UWP) of Outlook, Outlook Web Access (OWA), and the macOS desktop client.

Microsoft is building one desktop client that will be based on Outlook on the web. The leaked app is clearly in an early state, and Microsoft is even warning employees that it’s currently designed for “brave dog food” and doesn’t include an offline mode. Dogfood is a term used by Microsoft and other software companies to test and use early versions of their own code.

This early version has been leaked, but a definitive replacement for the Windows 10 Mail app may not come until next year. Windows Central reports that this client will likely enter a larger preview program by the end of 2021, aiming to replace the Mail and Calendar apps on Windows 10 by 2022.
