Scheduling and managing events using Outlook.com calendar
MS want's us to use macOS, iOS and Android as on all these platforms the family calendar is working just fine. I'm using Outlook for Mac and I can see and use the calendar as everyone expects.
But wait, as I'm already using macOS and iOS I'm also using iCould for Family Calendar and there was never such an issue. :p I own a M365 Family subscription and was already on the way to move from iCloud to Outlook.com. But the access to the family calendar within native apps (also Windows) is a must have and in my case a show stopper for moving to outlook.com as my family is heavily relying on it.
And I think MS does not really care about the consumers as they have a much better cash cow they need to take care about.
