  • Microsoft has developed a unified email experience for Outlook that unifies the various versions of the service onto a single application.
  • They have announced that the Mail and Calendar apps will look and function the same across desktop platforms using only a single version of Outlook.
  • Reviews of Microsoft's One Outlook app, based on leaked product images and information, suggest the app will be well-designed but users may find similarities to Microsoft's web-based Outlook.

Microsoft plans to unify its Outlook applications into a single user experience by creating Project Monarch, the company’s One Outlook app.

The Microsoft One Outlook app was originally scheduled to arrive in 2021, but that deadline was missed. The company is still working on Monarch, and the new program could arrive sometime this spring.

Project Monarch

Microsoft has developed a unified email experience called Project Monarch for Outlook, which brings together all of the various versions of the service from across platforms into a single app.

The new app will replace Outlook Web Access and the Windows 10 and macOS versions of Outlook, as well as the web version of Outlook.

Microsoft has announced that its Mail and Calendar apps will look and function the same across desktop platforms with a single version of Outlook.

Based on leaked images and information, early reviewers of One Outlook have praised its design, but some have suggested it borrows heavily from Outlook for the Web.

Microsoft will officially announce a new version of Microsoft Outlook during the spring and will likely release a first test version immediately. The update will appear on the Dev and Beta channels of the Windows Insider Program.

Public testing this summer

Microsoft is planning to release Project Monarch for public testing in the summer. The company seems to be positioning Project Monarch for a full launch by autumn, likely in conjunction with the Windows 11 (Windows 11 22H2 Sun Valley 2) update.

The release of the new app coincides with Windows 11 22H2, but it will also be available for download on Windows 10 and other desktop platforms.

The report says that Microsoft is unlikely to force users to migrate to the new experience until at least next year.

One Outlook will replace legacy Microsoft Office programs in the future, but users will have the option of choosing between One Outlook and the legacy experience at first.
