Limit the number of people per booking

When I run a research study I need to be able to control the amount of people who are booking onto it - right now I have to manually watch the sign ups via bookings then manually close the bookings page - this is really inconvenient when I am out of office and cannot track. This also has financial implications, if we have more participants than we anticipate then we have to pay more money.

  • As of today, it is not possible to automatically limit the number of participants per time slot — unless you use certain tricks or additional tools like Power Automate.

    You can automate the closing of the booking form or the deactivation of slots when a threshold is reached:

    1. Create a counter in a SharePoint or Excel list (e.g., number of registrations per study)
    2. .Use a Power Automate flow triggered for each new booking.
    3. Increment the counter.
    4. When the quota is reached:
      1. Send an alert to the organizer.
      2. Change the service availability or deactivate the booking link (by calling the Graph API or manually changing a publication column).
