I have developed a windows form calendar and I'd like to integrate it with Microsoft exchange server / Outlook Calendar. Basically my calendar has tasks/appointments in it for different users and I'd like it to sync with the outlook calendar of that specific user. I have looked online for solutions and was convinced to use Microsoft Exchange Web Service Managed API.
After reading tutorials about it, I can now successfully create an appointment in the outlook calendar from my calendar by following this steps i found online:

Now i am trying to delete that appointment using this steps i found online as well:

The problem i encounter is the Item ID. I looked online about it and still not sure how it works. Is automatically generated or i have to create these IDs myself as i add the appointments to the calendar.
