How to detect a user-deleted AppointmentItem?
 

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?

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.

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?

That sounds like a good approach.

Although comparing EntryID properties without using a special procedure
(like CompareEntryIDs in CDO or Redemption) can fail, especially for items
where you can get short or long term id's. And when an item is deleted from
an Exchange mailbox the EntryID on the item changes. It does not change when
deleted in a PST file.

I'd probably use ItemAdd on the Items collection of the Deleted Items
folder.

What is the "ItemAdd" that you mentioned?
And how to get the deleted Items folder?
Are all the deleted Items in the same folder? For example, the deleted
AppointItems and MailItems.

ItemAdd is an event of the Items collection. Each folder has an Items
collection. To get the Deleted Items folder you would use
NameSpace.GetDefaultFolder(olFolderDeletedItems), which returns a MAPIFolder
object. All of that is in the Object Browser, which you should learn to use.
It exposes all properties, methods and events for all objects in the object
model.

Any item that's deleted goes into Deleted Items unless it's "hard deleted"
(Shift+Delete). In those cases the items are just deleted. To detect that
you can handle the ItemRemove method of an Items collection for a folder,
which just tells you that something was deleted but not what. Then you'd
have to iterate the Items collection of that folder to see what's missing.

Try deleting some different types of items to see where they go, empirical
experimentation is really the way to go to find out how something works.
