Inbox Zero booking links give guests a public page where they can choose a free time, enter their details, and create a calendar event. The page respects your working hours, timezone, existing calendar conflicts, minimum notice, and meeting duration.
You can create one Inbox Zero booking link per email account. If you already use another scheduling service, you can instead save that external URL as your Calendar Booking Link so the AI can include it in scheduling replies.

​
Requirements

  • Connect at least one Google or Microsoft calendar.
  • Enable the calendars that should block busy times.

​
Set your availability

  1. Open Calendars in the left sidebar.
  2. Under Availability, choose the days and time windows when guests may book.
  3. Select Save.
  4. Confirm your timezone in the Timezone section at the bottom of the page. If you change it, select that section’s Save.
This is the account’s default availability. It also guides times the AI suggests in scheduling emails, even if you do not create an Inbox Zero booking link.
  1. On Calendars, find Booking link and select Create booking link.
  2. Enter the title in What guests see and a unique slug in Link URL.
  3. Choose a Duration and, under Add events to, the calendar where new events should be created.
  4. Optionally add a description. Video conferencing is on by default when the calendar supports it.
  5. Select Create. The Configure booking link dialog opens so you can review the remaining settings.
When Video conferencing is on, Google calendars add Google Meet links and Microsoft calendars add Microsoft Teams links. After creation, copy the /book/your-slug URL and share it. The active Inbox Zero booking link is also the link the AI shares in scheduling replies. Select Configure to edit the link’s details, including the minimum notice before a meeting. The default notice is two hours. Use the switch on the booking-link card to make the public page active or inactive. An inactive link cannot be booked and is not used by the AI. When an Inbox Zero link is active, it takes precedence over the external Calendar Booking Link field. Deleting the link is permanent and also removes its booking history. Pausing the link is safer when you may want to use it again.

​
What guests experience

Guests can:
  1. View open slots in their chosen timezone.
  2. Select a time and enter their name and email, plus an optional note.
  3. Receive a calendar invite and confirmation email.
  4. Use secure links from the confirmation to reschedule or cancel.
The host also receives booking notifications.

​
Troubleshooting

Connect a calendar and make sure at least one calendar is enabled.

​
No times appear on the public page

Check your weekly availability and timezone, minimum notice, and busy events across all enabled calendars. A disconnected calendar or temporary provider-availability failure can also hide all slots to prevent double booking. Confirm that the destination calendar belongs to Google or Microsoft and that video conferencing is enabled in the booking-link configuration. Changing the destination calendar can also change which conferencing option is available. Verify which Inbox Zero link is active. If no Inbox Zero link is active, review the external Calendar Booking Link field on the Calendars page.
