Introduction to Office 365 Calendar connection

Important To be able to connect OnceHub to your Office 365 Calendar, you must have a calendar in Outlook on the web for business (Outlook Web App), which is provided with Exchange Online.

Connecting OnceHub to your Office 365 calendar ensures a secure, real-time integration between your Office 365 calendar appointments and your busy time in ScheduleOnce. This means that ScheduleOnce bookings will flow seamlessly into your Office 365 calendar and busy events in your connected calendar will block out availability in your Booking page so you don’t get double-booked. Your calendar information is always kept private and calendar appointments and free/busy patterns are never revealed to Customers.


NoteWhile in beta, InviteOnce only supports Google Calendar integration.

Connecting and configuring Office 365 Calendar

Your Office 365 Calendar can easily be connected to your ScheduleOnce Booking pages. For each of your Booking pages, you can select the calendar in which bookings will be created, the calendars from which busy time will be retrieved, and any additional calendars you want an event created in when a booking is made.

Connecting OnceHub to your Office 365 Calendar only takes a few moments. Learn more
