What you need to connect Google Calendar or Outlook

  • A Caletus account on any plan
  • Your Google (Gmail or Google Workspace) or Microsoft 365 (Outlook) sign-in
  • Permission to connect outside apps to that account. Work accounts sometimes need IT to approve Caletus first.

How you'll know it worked

Your calendar is connected

Times you're busy on that calendar no longer show on your booking page, and new bookings are added to your calendar. Before a booking is confirmed, Caletus checks your Google or Outlook calendar once more, so a time you just filled can't be booked.
