How to detect that an AppointmentItem is a birthday?

Hello,

I've got code (not VBA but using the object model) to synchronize
appointments and contacts from Outlook to an external source. There is a
problem though because Outlook shows contact birthdays as calendar events. I
would like to detect and suppress these calendar events because the remote
system also has this logic and it leads to multiple calendar events existing
for each birthday.

I've looked at the docs but I can't see how I might detect that an
AppointmentItem is a birthday. Can this be done?

Ok... I think I found a way to get this from MAPI...

There is a named property (GUID {00062008-0000-0000-C000-000000000046}, ID
0x8586) that appears to be the Contact's name. This is present on birthday
and anniversary events but not on regular events.

Ugly, but no different to the code I already had to get contact email
addresses via MAPI (to avoid the security dialogs).
