I have pass my email address in attendeeInfo. This will return me only main calendar event. I need other calendar meeting also. How can i fetch other calendar (Sub calendar meeting). I have calendar-Id, But how pass it in my API call.

Answer 1

No GetUserAvailbility will only return events from the default Calendar folder, this is because it uses the FreeBusy information which is only published for the default Calendar Folder. If you want details of a secondary calendar then you will need to query that directly.
