What it means
Ghost meetings are one of the most common sources of wasted meeting room capacity. Someone books a room, the meeting gets cancelled or moved, but nobody releases the booking. The room shows as unavailable in the system while sitting completely empty.
The impact compounds quickly. As an illustration, if you have 10 meeting rooms and 3 are ghost-booked at any given time, you effectively have only 7 usable rooms. Teams complain about room shortages while rooms sit empty behind locked calendar entries.
A common solution is check-in verification. If nobody confirms their presence within the first 5-15 minutes, the system automatically releases the room, recovering capacity that would otherwise be wasted.
