> I think Windows 10 Mail could be the worst GUI application ever written

What makes you say this? I'm a heavy desktop user and find Windows 10 Mail to be the fastest and simplest way to interact with mail. It works perfectly with attachments, and calendar invitations, etc

It's a year or so since I used it, so I don't remember all the details. But off the top of my head: crashy, terrible IMAP implementation, mails often stuck in outbox, very incomplete keyboard shortcuts, links opened in Edge rather than default browser. I'm sure there was as lot more, but anyway I found it unusable.
