Is your intent to delete appointment items in other user's Calendars?

To get access to an item by it's ID, use the NameSpace.GetItemFromID method.
This will not allow you to get access to items outside of your mailbox
unless you have access to them via secondary mailboxes that are loaded in
your profile or via shared folders.

I'm working with Access and Outlook Meeting. Trying to figure out the best
way to create and delete meeting from Access. I've created the meeting
successfully, but haven't been able to delete and send a delete notice to
other meeting participants. I read something about using Global Object ID to
uniquely identify the meetings and have read this article
(http://support.microsoft.com/Default.aspx?id=899919).

To access the Global Object ID programmatically, use the following
information.Property Set Tag (Namespace)
GUID = {6ED8DA90-450B-101B-98DA-00AA003F1305}
Named Property ID: 3


But I still don't understand where do I need to put this, and how exactly
can I use the Global Object ID in my app (how do I code it?). Any help or
suggestions is appreciated...
