It has definitely improved. For one, I don’t think about my PST files for my personal use, which is nice. I’m torn on the new UI, sometimes, but usually only when I’m trying to go old school outlook power user on things.

But the add-ins have been pretty nice. I use one that does local header analysis and full header viewing SxS with the email. It’s handy.

You made a good point on the Mac version with multiple inboxes, too. My primary email machines are my phone and Mac, so it’s gravy all the way.
