Introduction to Exchange integration

Microsoft Exchange is a server that manages mailboxes, contacts, calendars and more. Exchange users never access Exchange directly, but rather through an email client, which can be an Outlook client on a PC or Mac, a mobile device, or web access via the browser (Outlook Web App, Office 365, etc.). ScheduleOnce integrates directly with Exchange for a seamless connection, allowing you to keep using whichever calendar access method you are currently using.

Main features

ScheduleOnce direct integration with Exchange enables a real time connection to your calendar, providing the following benefits:
  • Continuous sync no matter how you access your calendar: From your desktop or mobile, PC or Mac, your browser (Outlook Web App), or any email client (Outlook, Thunderbird, etc.).
  • Most Exchange versions are supported: Office 365, Exchange Online (hosted) and On-premises Exchange (versions 2007, 2010, 2013 and 2016).
  • Add new bookings to your calendar in real time.
  • Real time retrieval of busy time from your calendar to block your availability and prevent double booking.
  • Most shared calendars are supported both on the same domain and across domains.
This means that ScheduleOnce bookings will flow seamlessly into your Exchange 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.

The integration adheres to the strictest privacy and security policies. All credentials and data traffic are fully encrypted and secure. 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. The integration is based on EWS (Exchange Web Services) – a well-established and official Microsoft protocol.

Some Exchange servers have a relatively slow response time, and some apply a throttling policy, intended to moderate data traffic. To ensure fast performance and a smooth Customer experience, we employ a caching mechanism for the busy times in your connected Exchange calendar.
