Allow users only Reviewer access to the folder and make sure the resource mailbox has a delegate.

This will change in Exchange 2007 + Outlook 2007 to get you more of the control you want.

Hi,
Is there a way to stop all users from directly adding a meeting to a
resource in calendar. I need this to prevent someone from adding a meeting
in the same time slot as an existing meeting and not receiving a message that
there is a conflict.
I only want users to be able to create calendar events for resources by
requesting a meeting and adding the resource as part of the meeting request.

how can this be done?

Thanks
