Microsoft to build cross-platform Outlook from Edge bits

News  /  Published 08 Jan 2021  / 

Microsoft plans to produce a one-app-for-all Outlook that runs within the browser as a replacement for the various Windows, Mac, iOS and Android editions of the company’s premier email application, according to reports.

Code named “Monarch” and part of an already-announced project dubbed “One Outlook,” the web-based app would replace the desktop and mobile versions on all platforms, from desktop to laptop to tablet to phone. WindowsCentral, one of the first to report on Monarch, also said that the app will be based on the current Outlook web app at and

According to WindowsCentral and others, the Outlook web app may reach a preview milestone by the end of this year. However, it will not replace the Mail and Calendar applications baked into Windows 10 until 2022, with the substitution for Win32 Outlook even further out than that.

Been here, done that

The idea of one app able to run on multiple platforms — “write once, run anywhere” was one once-popular description, that one pitched as an edge for Java — has a long history in software development in general, and in Microsoft’s specifically.

Microsoft has taken more than one stab at this, the latest — before the current one — when it launched Windows 8 in 2012. Largely driven by a desire to meld mobile and desktop, the concept was branded a whole series of names, from “Metro” and “Modern” to “Windows Store” and “Universal.” Apps were to run on both Windows-powered smartphones (then a foundational pillar of Redmond’s overall strategy) and Windows 8 devices like PCs and tablets. And when Windows 10 loomed, Microsoft started calling them simply “Windows” apps.

It was confusing as all get out. And ultimately, all failed to reach the one-for-all app universe goal.

Thus a good question should be: What will make this attempt any different? Earlier goes at Windows universal apps have foundered because the results have been sub-standard compared to a native application (in other words, one written specifically for the OS). Although Microsoft will reportedly build in native OS support for some aspects of email — offline storage and the operating system’s own notification system, for instance — such promises have been made before … and fallen flat.
