As someone who doesn’t touch Windows anymore without hazard pay, part of the problem is a lot of the ancillary business apps are Microsoft as well. For example Outlook, which technically exists on Macs, but is missing half the features.
I shudder to think what extra features they cram into Outlook for Windows considering Outlook for macOS is already bloated to hell. I've had to use it for the past few months due to our company upgrading the internal AD version (or something) while they built out the support for native macOS Calendar/Mail, and I hated every second of it
Don’t worry. New Outlook on Windows is rapidly reaching feature parity with the Mac version, and as soon as they remove Classic Outlook from support, all versions will be equal(ly missing half the features).
