This will always be set to a duration of half an hour with the start time at the next full or half our on the clock.įor example Using New Items-> Appointment at 9:37 will create a new appointment starting at 10:00 and ending at 10:30. You cannot change the default duration of a Meeting or Appointment when using the “New Items” menu button to create a new Meeting or Appointment. I would like to have one hour as the default. When scheduling Meetings or Appointments, the duration defaults to half an hour.
