I have done just that. Gone back to my full on Apple ecosystem. All my contacts, calendars, reminded, todo’s are in one place. My unified inbox, sent box are all working brilliantly. My Microsoft 365 delivers perfectly to Apple mail. My contacts are all in one place and pop up as I need to send emails or make calls or reminders or appointments. It all works and is interconnected with my phone. The one App that needs me to run Windows benefits from my new Apple OS and the new Parallels so fully integrates. It makes Winds work like an Apple App. I am in heaven after 3 years of hell.
