Rebranded Mail & Calendar
Correct me if I'm wrong.
The so-called new Outlook is a rebranding of the Mail & Calendar apps, which are somewhat terrible.

* ribbon menu instead of classical menu
* shoving apps from micros~1 down the users' throats for all sorts of tasks, even when other apps were already set as default for these tasks
