In ScheduleOnce, you can disable the Office 365 Calendar invite email by going to Setup -> ScheduleOnce setup -> relevant Booking page -> Customer notifications and unchecking the box that sends the Office 365 Calendar invite email.
How does OnceHub connect with Office 365 Calendar?
When you connect your Office 365 Calendar to OnceHub via OAuth 2.0, OnceHub communicates with the Office 365 REST API (v2.0) and Microsoft Graph API using a token that is generated by Microsoft. Your sign-in credentials are never revealed during the connection process and are never stored by OnceHub. Once a connection is established, OnceHub reads or writes to your Office 365 Calendar in real time.
Can OnceHub connect with shared Office 365 Calendars or resources (Rooms)?
Your default calendar, sub-calendars (folders), and calendars that have been shared with you are supported.
Resource calendars are not supported yet for ScheduleOnce.
Can I set default Office 365 Calendar reminders when events are created via OnceHub?
Yes, you can configure default Office 365 Calendar reminders in the connected Office 365 Calendar.
Go to your OnceHub Account and click Profile in the left sidebar. Click on Calendar connection and use the Default Office 365 Calendar reminders drop-down menu to select the value that you want (Figure 1).
I cannot see my scheduled meeting in Office 365 Calendar
In your Office 365 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, then click the action menu (three dots) in the right-hand pane and select View Calendar event (Figure 2).
Why do my busy times appear in wrong time slots on ScheduleOnce?
This might be due to time zone differences between the account time zone in your Office 365 account and the time zone on your Booking page. To change the time zone:
- In ScheduleOnce: Go to the Overview section of your Booking page and edit the page's time zone.
- In Office 365: Click on Settings -> Options - > Settings -> Regional and change the time zone.
Reload/refresh the ScheduleOnce page to reflect the change.
I’m already connected with one Office 365 account. How do I switch to another?
Your account can only be connected to one calendar at a time. If you want to switch from one Office 365 Calendar to another, you will need to disconnect the previous one and then connect the new one.
Disconnect your calendar by going to your OnceHub Account, opening the left sidebar, and selecting Profile -> Calendar connection. Disconnect your Office 365 account and reconnect with the new Office 365 account.
NoteYou can switch your calendar connection accounts without having to switch your OnceHub Account.
What happens if there’s an issue with the connection?
During a connection failure, ScheduleOnce Booking pages cannot accept bookings. This measure is taken to prevent the possibility of double bookings.
To enable bookings, you must either restore the connection by reconnecting, or disconnect your calendar by clicking the Disconnect link and then reconnect again. Learn more about disconnecting a calendar
