Microsoft has previously said that it is making a new e-mail client for windows 10 and MacOS, and according to the latest information, the client will be optimized based on outlook on the web. In addition, Microsoft plans to phase out the uwp mail application launched in 2015.
It is reported that the internal code name of the upcoming windows 10 outlook is "project monarch", which is much smaller than the existing mail and calendar applications, but supports native functions such as action center and windows share.
Microsoft plans to invite members of windows insider to test later this year, but some users with azure organization accounts have successfully accessed the client after it was leaked on twitter.
As can be seen from the above screenshot, windows 10's one outlook application is completely based on the web version of outlook, and the client seems to use Microsoft edge to serve the web content. This app is still in the early stage of development. At present, it feels more like a web Wrapper Based on HTML5. You can use chrome or edge to install it, but it supports windows better.
