Using Classic Outlook on Windows for personal email, calendar, and contact management
Might have finally found a good solution 😁 I have been searching for ages now honestly. Wasn't really up for the hassle of installing some open source script or windows tool (I use mac).
You could try https://www.outlooktogcal.com/. Have been using is for a while now and works like a charm with my M365 account. Only one way outlook -> google calendar but events do update immediately so that's nice.
We're in this together I guess.
