Microsoft’s One Outlook has been leaked, and users are already hating it


Microsoft has been reported to be working on One Outlook for a while, but a new leak implies we’re closer than ever to getting our hands on the all-in-one email client.

With the exception of embedded window controls, the leak was discovered by Temmie on Telegram and then tweeted by @TomWarren. It seems aesthetically quite similar to the present Outlook Web service.

One Outlook (previously codenamed ‘Project Monarch’) will combine Outlook, Calendar, and Contacts from Windows 11 into a single app that works on PC, Mac, and the web to replace the company’s existing Outlook clients for desktop, which include Outlook Web, Outlook (Win32) for Windows, Outlook for Mac, and Mail and Calendar on Windows 10.


This isn’t the first time One Outlook has been exposed. The app first surfaced last year, but it was only available to Microsoft employees, so this is the first version we’ve seen that works with both work and school accounts.

Unfortunately, the new software doesn’t appear to operate with personal Outlook accounts just yet, but individuals with access to an education or work account can try out the One Outlook beta (clicking this link will download the setup installation file).

Microsoft has yet to announce when One Outlook will be officially rolled out to the public, but this leak does at least indicate that we might not have all that long to wait. While no official release date has been announced, initial conjecture suggested that the app would be accessible to Windows Insiders in April 2022 and then ready for a wide release in Q3 of this year, so things appear to be on track.


Microsoft needs to persuade certain people

Although a single system for Outlook programmes makes sense, especially given the large number of individuals still using the earlier Windows 10 operating system, this does not mean that everyone else is satisfied with it.

I’ve always particularly loathed using the integrated Mail app because of its clumsy design, and I’m certainly not alone, but there’s more to an email client than style.

While having everything in one place and with a consistent design may make life easier for those who use Outlook on a regular basis, there have been numerous complaints on social media about memory usage and the service being web-based rather than system integrated, which may cause problems for users with slow internet or bad connections.


The dependency on web apps in Windows 11 has also been criticised, resulting in poor performance and significant RAM utilisation. Unfortunately, people who use the present Mail application on Windows 10 or Windows 11 may find that it will be phased out in the months following the complete introduction of One Outlook, but I hope that a system-integrated choice will remain.

Microsoft previously indicated that both the classic and new One Outlook apps will be available at the same time to allow customers to manage their transition, but this indicates that the two may not coexist indefinitely.

Because Microsoft is leaning so heavily on online apps in Windows 11, less powered devices will feel more like a bloated Chromebook than a step up from Windows 10. Hopefully, Microsoft remembers to give native apps some love instead of focusing solely on web-based services.
