Microsoft graph Api not getting the original shared event

Question

I am using microsoft graph api to sync my calendar with outlook. All of the events which are created by me are synced perfectly but problem happens when the organizer is someone other than me. If I update that event, it updates on my calendar but it remains the same on the organizer's calendar. I don't want to update that event I just want to resync back to the original organizer's event when my start/end datetime are messed up but graph api does not return the organizer's event date time. It returns the datetime which I have updated to.
