Microsoft is working on Outlook Lite which will be a new lightweight version of Outlook.
Microsoft said Outlook Lite will be, "An Android app that brings the main benefits of Outlook in a smaller app size with fast performance for low-end devices on any network."
This comes after Thunderbird announced their mobile client last month, so there does appear to be a lot of development in the email client space right now. This is interesting since the email client space hasn't really had much attention since the advent of social media and mobile instant messaging.
However, I do feel Email is quite a good standard and is much better than today's walled garden instant messaging and social media platforms. Although, I must give credit to lots of fediverse projects (such as Mastodon and Pleroma) for trying to break down those walled gardens (as well as Delta Chat which is a Email app which acts like a instant messaging app).
