How Multi-Host Event Types Work
Multi-host event types let bookers schedule meetings that require more than one team member. Learn how primary and additional hosts work, why the distinction matters, and what happens when someone books a slot.
01 Jul 2026 · by Peter Grillet
A standard booking link only checks one person’s calendar. Multi-host event types check everyone who needs to attend, and only show times when all required hosts are available.
That means the person booking does not need to coordinate calendars manually, and your team does not need to chase availability after a time has already been chosen.
What happens when someone books
- calendr checks availability for every required host — primary and additional.
- Only overlapping free slots are shown on the public booking page.
- When a booking is confirmed, all required hosts are added to the meeting.
- One calendar invite is sent to the attendee, with a single meeting link (Google Meet or Microsoft Teams, depending on your event type settings).
- Calendar events are created for the hosts who need them, without sending duplicate invites to the attendee.
Primary host vs additional hosts
Primary host (one person)
The primary host is responsible for:
- The main calendar event and attendee invite
- The meeting link (Google Meet or Microsoft Teams)
- Booking notifications configured on the event type
- The booking page identity — their name appears first to the person booking
Additional hosts (one or more people)
They:
- Must be free at the same time as the primary host for a slot to appear
- Are included in the meeting when it is booked
- Can update their own availability for that event type (without changing the event type’s core settings)
- Do not receive a separate attendee invite or generate a second meeting link
Why the distinction exists
Without a primary host, calendr would not know:
- Whose calendar should create the official invite and meeting link
- Who receives booking notifications
- Which calendar settings (Google vs Microsoft, forwarding rules) should apply
- Duplicate calendar invites for the same meeting
- Multiple different meeting links (for example, two Google Meet URLs)
- Confusion about who the booker is actually meeting with
How to set up a multi-host event type
- Create a new event type, or edit an existing one.
- Enable Multi-host meetings in the event type settings.
- Choose a Primary host — select exactly one team member.
- Choose Additional hosts — select everyone else who must attend.
- Set availability as usual. Each additional host can also manage their own hours for that event type.
- Save the event type and share the booking link.
Availability and calendars
Availability
- The primary host
- All additional hosts you selected
Additional hosts can update their own availability for a multi-host event type without needing access to change the whole event type.
Calendars and meeting links
- The primary host’s calendar creates the main event and meeting link
- The attendee receives one invite with that link
- Other calendars connected to the primary host (or set up for forwarding) may receive host-only copies, without generating new links or re-inviting the attendee
What bookers see
- The event name and description
- A “Meeting with” list showing all hosts
- The primary host listed first
- Additional hosts listed below, in alphabetical order
- A calendar showing only times when everyone is free
Frequently asked questions
Yes. Edit the event type and select a different primary host. New bookings will use the new primary host’s calendar and settings. Existing bookings are not changed automatically.
Can the primary host also be listed as an additional host?
No. The primary host is always included automatically. Additional hosts are only the other people who need to attend.
What if an additional host updates their availability?
Only their own availability changes. The event type settings, primary host, and other hosts stay the same.
Bookings may fail to create calendar events or meeting links until their calendar is reconnected. Choose a primary host with an active calendar connection.
No. Multi-host requires all selected people to be available at the same time. Round robin assigns the booking to one person from a pool. Use multi-host when everyone needs to attend together.

Team Event Type fallback options (and when to use each)
Team Event Types let you control how bookings are routed across your team. Choose between Round robin, Default assignee, or Visitor select, and use fallback behavior to avoid losing bookings when a team member is unavailable.
How to reschedule an event
Reschedule any booking in seconds from either the confirmation email or the link inside the calendar event, then choose a new available time and send an updated invite automatically.
Manage Availability: Profile vs Event Type
Set your base availability at profile level, then choose whether each event type uses that default schedule or its own custom hours.
