That sounds like a good approach.

Thank you, Sue.
I can now cast the item.Parent property to an Outlook.MAPIFolder object, and
compare its EntryID with the former folder's EntryID, so as to determine
whether the item has been deleted.

Do you have some more safer/smarter method to do this?

Deleting the item just moved it to the Deleted Items folder. It has the same EntryID there that it did in its original location. Check the Parent property of the item that GetItemFromID returns.

I deleted an AppoitmentItem using the Outlook GUI. But still I can get the
AppointmentItem with the NameSpace.GetItemFromID() method. I guessed the
method should have returned a null value but I was wrong.

Then, how can I detect whether an AppointmentItem with the speciied EntryID
has been deleted by using the GUI?
