Outlook Copy Appointment To Another Calendar. Click import from another program or file, and then click next. To share the calendar to others, there is no need to copy the appointment, you can just clicking the button share calendar in outlook 2016 client under calendar tab.
Sadly, this will only result in the subject being copied in a new appointment in case of an all day event. That means any new appointments you add to one calendar won’t copy over to your other calendar.
