We have create a leave request form. As part of the workflow if approved it will email the user with a ICS file so they can add it to their calendar. In our department we have a Exchange resource calendar for staff to add their vacation, conference, etc. We would like to figure out a way to add this resource calendar to the ICS file. When the staff members "Accepts" the calendar event its added to their personal calendar and added to the resource calendar. At this time we want to avoid connecting to exchange directly as part of the workflow.
