We have several resources in our company that we manage using outlook caledar. Each resource has an active directory account and is setup to automatically accept new calendar invitations. The system works fine except for one issue. When a user reserves a resource for all day, other users can still make appointments during that day with out receving a conflicting appointment error. This only happens when a user has checked the "all day" box on the appointment details.
Is there a way to prevent this from happening? Idealy, I would like for Outlook to prompt the user with a "schedule conflict" in these cases.
