Hi team,


I am getting below error from postman when I try to perform the Patch operation

id used after /calendars is the iCalUId generated while creating calendar event and id used after /events is the event id generated.
Please guide us what is the correct way to use the api , as tried multiple. ways  and still facing the error

"error": {


"message""Id is malformed."



IS the iCalUId which I am supplying in the Patch call incorrect ? 
What is the way to update calendar for a user which has multiple invites sent and we need to update one single instance of his calendar from ms graph api update event
