In our business, we have shared calendars that users from all over the country can use to book training rooms. The problem is that people book the training rooms in advance and when they do not need the facility, they forget to cancel the booking prior to the event which then does not "release" the resource (we do not physically have a body managing the rooms). I want to be able to set up an automated reminder which sends an email to the person that booked the resource and requests that they confirm the booking one week in advance... Some users are on Office 2003 whilst others are on Office 2007. In our business, we have shared calendars that users from all over the country can use to book training rooms.
