OnceHub communicates with your Exchange Calendar using the Exchange Web Services (EWS) API, a well-established official Microsoft protocol. All credentials and data traffic are fully encrypted. Learn more about how your sign-in credentials are stored and protected by OnceHub
In this article, you'll learn how to connect your OnceHub Account with your Exchange Calendar.
To connect to your Exchange Calendar
- Sign in to your OnceHub Account.
- Open the left sidebar, click Profile, and select Calendar connection.
Note If you are connected to any other calendar, you will need to disconnect first. Existing bookings that have not yet taken place will not be added to your Exchange Calendar after you connect.
- Click the Connect button next to Exchange Calendar (Figure 1).
- The Connect to Exchange Calendar pop-up will appear (Figure 2).
- Enter your email address and password, as you normally would to sign into your mailbox via Outlook or any other method. Click Connect.
- If the connection is successful, the pop-up closes and you should see confirmation that you are connected to your Exchange Calendar (Figure 3).
- If you're using InviteOnce, you'll now be able to begin scheduling meetings by clicking the Schedule a meeting button in the What's next? section.
- If you're using ScheduleOnce, you have the option to configure the ScheduleOnce advanced integration settings. You can also click the Continue setup button in the What's next? section to access more options in ScheduleOnce.
You're all set! You can now configure your Exchange Calendar connection.
Connection issues requiring additional information
Even if your credentials are correct, the connection might not be successful due to various Exchange configurations. If you see the following screen (Figure 5), additional information will need to be provided.

The value to enter in the User name field depends on your Exchange configuration, and can be any of these three options:
- Leave blank—not required for many Exchange servers.
- Try entering your email again, which some Exchange servers accept as a user name.
- Enter your full Domain\UserName you would use to sign into other Windows systems:
Click the Connect button. If you're still not connected, make sure you have entered all the values as above, making sure all the formats and slashes are 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
