In this article, you will be given step-by-step instructions to connect your OnceHub account with your Exchange (Outlook) Calendar, using our personal Exchange integration.
To connect to your Exchange Calendar:
- Sign in to your OnceHub account and navigate to ScheduleOnce.
- Go to Setup and open the left sidebar. Select Integrations -> Calendar integration.
- If you are connected to any other calendar, you will need to disconnect first. Existing bookings that have not yet taken place will be added to your Exchange Calendar after you connect.
- In the Exchange Calendar box, click Connect. The Connect to Exchange Calendar popup will appear (Figure 1).
- Enter your email and password, as you would normally log into your mailbox via Outlook or any other method. Make sure your credentials are correct in order for the authentication to succeed.
- If your Office 365 account is set up with 2-step verification, you must create an app password first, and then use this special password to connect your ScheduleOnce account to your Office 365 Calendar.
- If connection is successful, skip the rest of this article and configure the Associated calendars section of your Booking pages.

Even if your credentials are correct, the connection might not be successful due to various Exchange configurations. If you see the following screen (Figure 2), additional information will need to be provided.

- Enter your full Domain\UserName as you log into other Windows systems:
Click the Next button and the connection should work now. If you are still not connected, make sure you have entered all the values as above, making sure all the formats and slashes in the right places.
If the connection still fails, search your organization's internal knowledge base or contact your IT support, as there are many possible Exchange configurations and settings. Learn more about Exchange connection troubleshooting
