For each of your ScheduleOnce Booking pages, you can select the calendar that bookings will be created in, the calendars that busy time will be retrieved from, and any additional calendars you want to create an event when a booking is made. 

When you use InviteOnce to Invite to self-schedule or Schedule on behalf, availability will be retrieved from your Office 365 Calendar. The InviteOnce algorithmic scheduling engine works out all the available time slots based on your meeting requirements.

Privacy and security

When you connect OnceHub to your Office 365 Calendar, all credentials and data traffic are fully encrypted. The integration uses the permissions Users already have when viewing calendars (for example: only free/busy), so no new information will be accessible to them.
