How to overwrite Outlook calendar events

So I have this function that creates events on my outlook calendar based on a Dictionary (Later will be data from a database):

def addevent(events):
import win32com.client
for item in table.keys():
    start = '2012-' + item + ' 18:35'
    subject = 'Event Name' + str(table[item])
    oOutlook = win32com.client.Dispatch("Outlook.Application")
    appointment = oOutlook.CreateItem(1) # 1=outlook appointment item
    appointment.Start = start
    appointment.Subject = subject
    appointment.Duration = 20
    appointment.Location = 'Virtual'
    appointment.ReminderSet = True
    appointment.ReminderMinutesBeforeStart = 1
    appointment.Save()
return

However, the issue is that when I re-run it, it adds the same events at the same time but I want it to overwrite events at the same time/ skip the same events. If that makes sense.

After you save the appointment, retrieve its EntryID property and store it. Next time, if the entry id is available, use Namespace.GetItemFromID to reopen the appointment. Otherwise create a new one like you do now.
