Appointments 'collapsing'

Hello! I hope someone can help me understand how Outlook 'collapses' two

appointments into one. Below is the scenario

1. I send an email from GMail with an embedded meeting invitation.

2. Outlook receives 2 messages (that's what I see in the Inbox). Don't know

why two - whether that's how GMail sends it or the way Outlook interprets the

invitation.

3. Calendar gets a 'shadow' item corresponding to the meeting

4. I accept both items in the inbox.

5. Calendar's 'shadow' item becomes normal.

In effect what happened, the two items from the Inbox collapsed into single

item in the Calendar.

I need to detect this. But my code gets two 'item added' events with

different IDs for the Calendar folder and I know of no way to figure out they

are actually the same.

So, how does Outlook do it?

I'd appreciate any and all information.

Thanks,

Well, sometimes posting a question helps finding an answer :) The

GlobalAppointmentID property is the key, not the EntryID.

Hope this will be useful to others :)
