> From the perspective of market fit and success, there are countless less-technical business users who swear by Outlook. And I find Outlook painful enough that I use Windows Mail at work. That only because my team disabled EWS for using about anything else. > They are not familiar with anything other than the kind of endless thread top-posting in odd encodings that Outlook all but ensures users will do -- that's e-mail to them. Why stop selling it to them? Ahhh, the old "embrace, extend, extinguish" by breaking other email clients among other things. For Corporate America (as opposed to startups), Outlook is email. Well, Gmail, Yahoo, Thunderbird and Roundcube can view Outlook-composed email fine now since IE stagnated and Firefox/Chrome beat it. (assuming Outlook used IE for rendering, I don't work on the Outlook desktop client and joined after Edge went Chromium). And Outlook still can't inline post, because Microsoft borked the "standard" and built an email client for corporate users not Unix nerds.
