Connecting to Exchange (personal credentials)

In this article, you will be given step-by-step instructions to connect your ScheduleOnce account with your Exchange (Outlook) Calendar, using our personal Exchange integration.

To connect to your Office 365 Calendar:

1. Sign into your ScheduleOnce account, go to Setup, open the left sidebar and select Integrations -> Calendar integration. If you are connected to any other calendar, you will need to disconnect first. Don’t worry, existing bookings that have not yet taken place will be added to your Exchange Calendar after you connect. Click the Exchange Calendar Connect button.

If connection is successful, skip the rest of this article and configure the Associated calendars section of your Booking pages.
