You can prevent back-to-back meetings getting scheduled with you using a Meeting Buffers in your available hours for meeting. Here is how to set it.

Step 1: Go to "Appointment Booking"

Step 2: Click “Manage Appointment Types” on Booking Page of your choice.

Step 3: Click on "Change Hours" on Appointment Type for which you want to set meeting buffers.

On your right you can see the list of certain policies. By default, there are no breaks or buffers set.

Step 4: Check "Ensure there are breaks between scheduled meeting" box.

Select the time increment and click the save button.

Now you’re all set for the selected Appointment Type. This setting is not global. You’d have to set the break / buffer interval for every Appointment Type. This allows for more flexibility in customizing your availability based on type of meeting you are having.

Happy Scheduling!
