How are meeting appointments connected and how can I use this connection?

Yes, cou can. The Appointment. ICalUid property ties meeting instances together accross mailboxes.

You need to check the mailboxes of the participants of that meeting and search their default calendar folder for items with the Appointment. ICalUid set to this value.

When you (as the origanizer) modify an appointment, Outlook prompts you to send a meeting update, which the recipient can accept. What exactly are you trying to do and why?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
