Appointments can be moved one of two ways:
Right-click on the appointment and select Move Appointment.
Click on the time slot you want to move the appointment to, or right-click and select Move appointment to <date>.
Verify the appointment listed is the appointment you'd like to move, and select Continue to confirm the move.
Click on the appointment to Drag and drop the appointment to the new time slot.
You can change the appointment's duration by holding down the bottom edge of the appointment and dragging it up (to make it shorter) or down (to make it longer)
