I did, it was a genuinely good little lightweight UWP email app. Now they've turned it into a bloated ad-ridden Outlook webview app.
Microsoft does plenty of cool things these days, but it's bizarre how they're pushing these little Windows monetization efforts like it's some garbage F2P mobile game.
I’ve been helping people to Thunderbird. Most people are like: Mail>Thunderbird>New Outlook thingy. Good enough for me ;)
Like it took me long until I figured out how to show message size, filter by date and then sort it by message size. Of course, the Mail thingy wasn't able to do something like that, but I remember waaaaaaaaaaaaaay back, that Communicator (that Mail program which came with Netscape / Mozilla) was way simpler to use than Thunderbird. But maybe my memories are hazy as this was like ~15 - ~20 years ago.
But then I had to use the web interface to do anything with filters, so when I had to reinstall Windows I didn't bother configuring it again. And now everything is on Teams anyway.
