How to determine the oldest date for startDateTime for List calendarView

Question

We are developing an app to integrate Outlook calendars, is there a way to find out the farthest date I can supply to List calendarView for the parameter startDateTime? our aim is to have the Users manage all events in our app and and I frequently get date range errors and right now I just hard-coded it to fetch from 2016 onward.

It may also apply to how far ahead in the future I can supply to the parameter endDateTime?

Thank you and appreciate the help.

Answer 1

Use me/calendar/events?$orderby=start/dateTime and get the first record dateTime in Start. From there you can use that dateTime in /calendarview endpoint.
