We receive Error when we pull the events from Office365 calendar Using Outlook Rest API

Question

This is the error that I receive when I try to pull the events from Office 365. Using the calendarView API end point to pull the events

{ "error": { "code": "ErrorItemNotFound", "message": "The specified object was not found in the store." } }

Answer 1

The error is telling that the object doesn't exist in the given store/mailbox.

Try the following:
(1) Make sure you can access the given item in Outlook
(2) If yes, try accessing the item using Graph API and locate it's ID using Graph Explorer/POSTMAN. Then open the item programmatically using the above collected id and see if it works.
