New Outlook | Microsoft Community Hub (opens in new tab)

I have been trying to move to the new Outlook for over a year, but I always end up having to revert to Classic Outlook.The new Outlook is slow, particularly when opening windows, and some features appear to have been designed to look modern rather than to be practical. The design also makes it difficult to work efficiently: there are too many colours, the visibility of important information is poor, and the overall experience feels more like using the web app than a proper desktop application...
