Recently I moved our room booking system to a simple online process - each room has it's own site containing only a web-part calendar.
Is there any way at all, to make sure that nobody can book any time slot in a certain day, if somebody has already booked an all-day event for that day?? A few people are struggling with this.
Yesterday I had an 8 hour meeting in one of our rooms. Had the meeting down on the calendar as an 'all-day event'. But, this didn't stop people from being able to book different slots through the day. Some people were failing to notice the all day booking banner underneath the date.
