You can use OnceHub without a connected calendar. In this case, you will still be able to accept bookings from Customers when working with ScheduleOnce. However, you will not be able to schedule meetings using InviteOnce (Note that InviteOnce currently only supports Google Calendar).
If this is an option you are interested in, you should consider the differences between working with a connected calendar versus working without a connected calendar:
|Working with a connected calendar||Working without a connected calendar|
|Booking creation||All bookings are directly created in your personal calendar, based on your availability and booking settings.||All bookings are created in ScheduleOnce and are available in the Activity stream.|
|Calendar event for the Owner||The booking automatically creates a calendar event in the Owner's calendar.||The calendar event is sent in the scheduling confirmation email and can be added to the calendar manually.|
|Cancel or reschedule by the User||When connected to Google Calendar or Exchange Calendar, the User can cancel or reschedule directly from the connected calendar.||Bookings can be canceled or rescheduled through the ScheduleOnce activity stream.|
|Booking reassigned by the User||When a Booking owner is connected to Google Calendar, any of the Booking owner’s one-on-one meetings can be reassigned to any other User who also is connected to Google Calendar.||Any of the Booking owner’s one-on-one meetings can be reassigned to any other User who is also working without a connected calendar.|
|Calendar event for the Customer||Depending on the Customer notification settings, a calendar invite from the Owner's connected calendar can be automatically sent to the Customer.||The calendar event is sent in the scheduling confirmation email and can be added to the calendar manually.|
|Link to calendar in the Activity stream||There is always a link to the calendar event in the Owner's connected calendar.||There is no link to an external calendar event.|
|Blocking availability with Busy time||Busy time can be retrieved from any calendar you have access to in your calendar account:|
Google, Outlook and iCloud Calendar users can retrieve busy time from calendars under their ownership and calendars that have been shared with them.
Office 365 Calendar users can retrieve busy time from calendars under their ownership.

|Only bookings made via the Booking page can block availability for that booking page.|
When a User is using multiple Booking pages, they could get double-booked: When the calendar is not connected, scheduled bookings in one Booking page do not block the time on the other Booking pages.
|Scheduling meetings||You can schedule meetings for yourself and/or for other users.||Not supported.|
|Meeting creation||All meetings are directly created in your personal calendar, based on your availability and meeting settings.||Not supported.|
|Receive bookings||Regardless of your calendar connection, other users can schedule meetings with you as long as they have at least free-busy access to your calendar. You will be added as a guest to the calendar event.||Not supported.|
Note When integrating with Exchange, Office 365, Outlook, Google, or iCloud Calendars, OnceHub connects to your personal calendars in real time and uses them as its calendar. This approach is highly appreciated by our Customers and has numerous advantages over using ScheduleOnce without a connected calendar.
