The multiple hosts algorithm (Collective or Multi-host scheduling) is to be used to pool team members’ availability. The collective/multi-host booking page shows appointment slots only when all team members (all hosts) are available. If any host is not available when the other hosts are, that time slot will not be shown as available. When an invitee schedules a meeting, all team members are added to the calendar meeting invite.
