How to Prevent Duplicate Calendar (List) Items - SharePoint 2010


  • I'm trying to create a calendar that will serve as a Conference Room reservation system for my department. 

    Pain Point: Duplicate reservations are constant. 

    Needed Solution:  A calendar/list that - when creating a New Item - has the ability to check the existing List Items for duplicate Start Date/Time and End Date/Times.

    Use Case to consider: The solution would have to consider any time in between the Start and End times (for example - existing List Item runs from 9am-11am......but someone wants to create a New List item that has a start and end time of 9:30-10:00am ).

    Any thoughts how this solution could be built?
