Exchange Calendar FAQs

OnceHub communicates with your Exchange Calendar in real time using an encrypted and completely secure EWS connection (Exchange Web Services).

What does Exchange Calendar integration mean?

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.). OnceHub integrates directly with Exchange for a seamless connection, while you keep using whichever calendar access method you are currently using.

Establishing a connection FAQs

How do I connect my Exchange Calendar?

  1. Open the ScheduleOnce User app.
  2. Go to the left sidebar -> Calendar integration. If you are switching connections, you must first disconnect from your previous connection first.
  3. Click the Connect button under Exchange and provide your credentials.

I already have a calendar connected. How do I switch to another?

Your account can only be connected to one calendar at a time. If you wish to switch from one calendar to another, or from one connection method to another, you will need to disconnect the previous and then connect the new. In your OnceHub account, open the left sidebar, go to the Calendar connection page, click “Disconnect” link, and then connect to another calendar or connection method.

Working with the connection FAQs

Can I disable the Exchange calendar invite that is sent to my customers?

You can disable the Exchange calendar invite email in ScheduleOnce -> Setup -> Booking pages -> Customer notifications (or Setup -> Event types -> Customer notifications if using Event types), and uncheck the box that sends the Exchange calendar invite email.

I cannot see my scheduled meeting in Exchange

In your Exchange calendar, make sure that the calendar in which your meeting was scheduled is selected. Find it in the calendar list in the left bar and click it to select it. You can also select the activity in the ScheduleOnce Activity stream and click it to see a direct link to the Exchange calendar event on the right hand pane.

There is a time offset between my calendar and ScheduleOnce

This might be due to time zone differences between the account time zone in your Exchange account and the time zone on your Booking page. To change the time zone:

  • In ScheduleOnce: Go to the Time zone subsection in the Overview section on your Booking page, select the new time zone and save.
  • In Exchange: Go to the settings in your calendar (Outlook, browser or other email client) to update the time zone. Reload/refresh the ScheduleOnce page to reflect the change.

Can I set default Exchange Calendar reminders when events are created via ScheduleOnce?

Yes, you can configure default Exchange Calendar reminders in the connected Exchange Calendar. To do so, you simply select an option from the Default Exchange Calendar reminders drop-down list under Setup -> Left sidebar -> Integrations -> Calendar integration.

Can I update ScheduleOnce meetings in my connected Exchange Calendar?

Yes, when you are connected to Exchange Calendar, you can select whether changes made to ScheduleOnce events in your connected calendar are reflected in ScheduleOnce. When a ScheduleOnce event is deleted in your Exchange calendar it will cancel the booking in ScheduleOnce. When a ScheduleOnce event is moved in your Exchange calendar, the booking will be rescheduled in ScheduleOnce. Learn more about cancel and reschedule form within your Exchange Calendar
