I was a long-term Mac user (>10 years) and switched do Windows and Linux. I will „never“ go back to a Mac.
One of the reasons was that I couldn‘t make Mail.app working with Exchange/Microsoft 365 (especially shared mailboxes) and the other that Docker is so slow (volumes with many files are unusable). It‘s sad to not have a single OS for everything. I now need Windows to write e-mail and Linux to do my work.
I would have kept a Mac and installed Linux in dual-boot but I need something that „just works“ because I need to do work sometime and I wasn‘t sure enough that it will work smooth.
I used to use my personal mbp for work, since I found windows extremely annoying for operations work (it's only getting slightly better with alacritty and windows terminal...) and my client wouldn't provide me a mac. Almost two years ago I tried installing Arch linux on the laptop they provided which was gathering dust, and I was surprised that almost everything worked perfectly out of the box (except for the fingerprint reader).
They're using Office 365 too, so I tried using it in the browser (Firefox) and I loved it so much that I can't use the local outlook client anymore. It just feels sluggish, and I hate that I have to let go of the slider when scrolling to see the message list update. I don't think shared mailboxes are handled very well, though.
I agree, being grown up with Linux/Mac and then starting to use Windows is like „why can‘t i do that through a terminal“ all the time.
Online Office 365 is not a workable solution, because I‘m a contractor and need to use up to 3 exchange accounts within a single day. And that‘s a lot of logout-login if done in the browser. Chrome (profiles) is not an option for me.
