We have a calendar syncing feature using the API outlined msdn.microsoft.com/en-us/office/office365/api/calendar-rest-operations
Through the 365 Calendar UI you are able to add a public, read-only calendar via 'Add Calendar -> From internet' dropdown. These calendars appear under 'My Calendars' even though you can not create or edit events on them through the 365 UI. (However, you are able to create events by sending a POST through the API.)
This has caused an issue where an on-premises Exchange calendar is shared to 365, and when we create events on that calendar via the API (to the new calendar on 365), they are later deleted (presumably by the exchange server).
I would like to know how to get only the calendars that the user has write access to, via the API.
