A leaked version of One Outlook is available. Over time, the application will replace all Outlook versions.
In 2021, Windows Central shared leaked images of One Outlook, a long-awaited Microsoft project. The tech giant wants to replace all versions of Outlook with a single application.
Currently, companies’ Outlook versions vary. Some work with older licences, and therefore older versions. The functionality differs per version and operating system. Microsoft hopes to streamline the user experience with One Outlook, a universal app.
At the beginning of 2022, anonymous sources told ZDNet that Microsoft would be releasing the first version of Outlook One this spring. The sources predicted that Windows Insiders (members of Microsoft’s beta programmes) would receive an invitation. That invitation has yet to be sent. Nevertheless, the first version One Outlook is available. Not officially, but through a leak.
The download link (here) is circulated on Telegram. It’s unclear how the source got hold of the link, but the app seems to work fine for users with an Outlook account for business or education. Personal email accounts do not work.
The leaked version is almost identical to the web app on Outlook.com. There are minor differences in appearance. Website XDA shared a number of comparative screenshots. The top banner can be changed to a traditional Outlook-style. The buttons of the header are formatted in a Windows-style, which provides a familiar look. Several text fields and buttons are marked with ‘preview’ and ‘beta’. That’s to be expected from a prototype.
In terms of functionality, the app works the same as Outlook.com. One Outlook is a web version as well. This allows Microsoft to eventually push the app to all Outlook users, including those on macOS and Linux.

Microsoft has yet to officially announce the project. ZDNet’s sources expect the live release in October this year. From then on, One Outlook should replace the Mail and Calendar apps in Windows 10 and Windows 11. Optionally at first, and standardized over time. We expect the macOS version to appear later than Windows.
