The UID value is stored in a binary MAPI property that you can see using
OutlookSpy:

Tag num: 0x80370102
Tag sym: 0x8037
DASL name:
http://schemas.microsoft.com/mapi/id/{6ED8DA90-450B-101B-98DA-00AA003F1305}/00030102

You will need to use CDO, Outlook 2007 or Redemption to access that property.

After creating an iCalendar file and adding it to my calendar. Is
there a way to retrieve the iCalendar's UID from within VB? I looked
in Outlook Spy and didn't notice my UID field anywhere in the
appointment. I'm assuming Outlook must have a way to either store it
or translate the UID to their appointment id field as Outlook can
obviously update previously entered iCalendar appointments.

A search of the internet and this group found me a post by Hoffman,
but he was never answered.
