Sync multiple calendars in one
Maybe MS Flow can help. Check https://flow.microsoft.com/en-us/templates/?category=eventsAndCalendar&sort=properties%2Fstatistics%2Finstantiations.
It is hard to sync calendars in both ways, and in outlook there is no trigger 'When event is deleted', but all new meetings you can send automatically to one calendar.
KamiA Thank you for your suggested solution. That looks like a clever, free way to get sync working.
Unfortunately for me I'm also looking for something that works cross platform, since most of the time I'm not using Windows to do my work. I might try to get this working in a Windows system, just for this, but otherwise my search continues.
If a paid solution is an option, we sync across Office 365, outlook.com, Gmail, and Gsuite accounts. Totally cloud based. Nothing to install. Nothing to configure in Outlook. (On-prem Exchange requires an impersonation service account).
