How to Copy or Move Appointments to a Different Outlook Calendar

If you have more than one calendar, you can easily move, or copy, appointments between them.   Click and hold the appointment you want to move and drag it over to a different calendar in the list on the left.  To copy it, do the same thing but hold down the CTRL key while you are dragging it.  You will see a “+” indicating that it will copy instead of moving the appointment.
