To add to my own post what made me switch from M365 away in the first place besides the admin madness:

- No catch-all (yes, I use my own domain just for me, and I want a catchall to my mailbox)

- Outlook 365 webinterface becoming buggy and shitty in so many ways

- I had 2 domains set up (one private, one business) but O365 would not display which email a given was used as target (just display my name), nor would it let me choose FROM which Email I want send/reply to a mail

- O365 required re-authentication every 24h or so, but I always keep the webinterface open in my tab 24/7

Additionally, I had a Bitwarden paid subscription and looking for another VPN subscription, plus a commercial AI subscription. Proton is has all of that in a one-package deal.
