Auto-release frees a booked desk or room when nobody confirms within a grace period, returning it to the pool for others to book. It is the enforcement half of a no-show policy: the polite rule everyone ignores becomes a system behaviour nobody has to police.
With meeting room no-shows commonly running 25 to 35%, auto-release is often the single biggest capacity recovery available: space returns to circulation the moment it goes unused, without a single awkward conversation.
