I am using the Flow templates for both creating and modifying events in Office 365 and having them flow to Google Calendar. So far, this is working well, however, when I delete an event in Office 365, the event does not get deleted in Google Calendar. Is this something that is coming for these two applications?
Also, if there is a way to achieve two-way sync of calendars without having an infinite loop of events, that would be excellent to know as well. Ideally, I'd like both calendars to sync simultaneously, but I have yet to find a way to acheive this, either through templates or building my own Flow (although, perhaps I don't know enough programming language to build my own?)
You can now set up templates that accomplish these scenarios: https://docs.microsoft.com/business-applications-release-notes/April18/microsoft-flow/calendar-sync-... -- these include triggers on events being deleted.
