If you have a calendar linkage in Jicoo and the candidate dates are not blocked, first check to see if the "Calendar to check for appointments" is checked in the calendar linkage.
If there is no problem with the linkage,In order to block an appointment when scheduling with Jicoo, the Outlook calendar must be set to publish as " Tentative," " Busy," or " Away".
*Please note that if you set "Available" or "Working elsewhere", the appointment will be displayed as a candidate date and registered as an appointment.
