Preventing double-booking across multiple calendars is available on the Mixmax Small Business plan and above. Check out our pricing page for more information.
Using the Share Availability enhancement, you can easily prevent double bookings. Just click the box next to Prevent double bookings on this calendar, as per the screenshot below.
If you are coordinating meetings with multiple people or even across an entire team, you can create a Calendar and select the option to prevent double booking across multiple calendars. You'll see the option to Prevent double booking at the bottom of each Calendar you have created.
Double booking will prevent events from getting scheduled on the specific calendars you add to Prevent double booking. If the person you add uses multiple Google or Outlook calendars, you must add them all in this section to prevent double booking.
Simply type the name or email address for the calendar you want to add to prevent double booking, and we'll show only times that work for all of the calendars.
You must have Read/Write access to the Google or Outlook calendars to enable this setting. To learn more, see how to share calendars and permissions.
