What, you don't think people were flocking over to Mutt?
When I was first getting into Linux, I liked Evolution a lot, though admittedly I haven't used it in awhile. Honestly I haven't really used Mutt in awhile either; webmail is just easier.
Evolution is great; it's also had outlook EWS (including Oauth2) support for several years now. I am still mystified as to why Thunderbird is so much more popular (though nice to see that thunderbird is getting some much needed TLC more recently).
