I used the The sharepoint 2010 Calender list for "Use calendar for resource resrvation" by activating the GroupsWorkslists feature.
I have booked a recurrence event from 11:30am to 12pm for a paticular resource.
But i find another person is able to do a normal booking for the same resource from 11:00am to 12:30 pm for the same date.
This overlapping of time slots is possible only for the recurrence event.
Please suggest how to avoid this overlap.
