Microsoft's 'One Outlook' email client may arrive in preview this spring
Microsoft's new email client for Windows is almost preview ready.
What you need to know
- One Outlook (Project Monarch) is almost ready for preview.
- It could arrive as soon as this March.
- This is Microsoft's (eventual) replacement for Mail & Calendar on Windows 11.
Last year, Windows Central reported that Microsoft was working on a new Outlook client, codenamed "Monarch" and based on Microsoft's Outlook Web experience. Originally, Microsoft expected to begin shipping the app in preview in the summer of 2021, and replace the Mail & Calendar apps on Windows 11 later this year. For whatever reason, that initial preview never arrived.
Now, a report from ZDNet's Mary-Jo Foley has shed some light on the whereabouts of Project Monarch, stating that the app is still in development and may arrive in preview as soon as this spring. Microsoft does still intend to replace the Mail & Calendar apps, though that may not happen this year. Instead, Microsoft will place the new Outlook client alongside the Mail & Calendar apps while users get used to the new experience.
Microsoft has been hard at work on its new One Outlook client for well over a year at this point. It's Microsoft's goal to consolidate and unify the Outlook app experiences on desktop with a single client that's powered by the web. Microsoft hopes that this new client will eventually replace Mail & Calendar as well as Outlook Win32, though that plan is much further out.
For now, we're getting close to the first preview release of One Outlook, which Foley states will roll out first to Insiders in the Dev and Beta Channels in late March or early April. It'll then make its way to the Insider Slow Channel sometime in the summer.
