The beta version of Outlook.com is already about 100 x better than the regular version, and the team has just added another feature to take it to the next level.
Outlook.com beta now features a tabbed user window interface which makes it super easy to reference a number of emails when crafting a reply for example.
The tabbed window appears to be the default for the New Email window, and can be accessed for other email by using the Open in New Tab option in the right-click menu.
The improvement unfortunately further demonstrates how far Microsoft’s UWP mail app has fallen behind, with less than half the features of their web app.
The Outlook.com beta can be accessed by flipping the toggle at the top right of the screen in the web interface.
Thanks Ben for the tip.
