Delete recurring appointment with MAPI DeleteMessages()?

[Eric]

Whenever I try and delete a recurring appointment item using
IMAPIFolder:eleteMessages() it fails with this error:

MAPI_W_PARTIAL_COMPLETION

The item is not deleted, and none of the ocurrences are deleted
either. I'm just trying to delete the entire item. I am able to use
the same code to delete any other item, just not recurring appointment
items. Do I need to do something special to delete them, maybe remove
the IsRecurring (whatever MAPI property it maps to) flag first?

I notice I am able to delete these items using Outlook Spy's
IMAPIFolder GUI. I view the "Contents Table" tab and then click the
"delete" button, and it removes it without any errors. Maybe I'll try
MDBView also since that lets me get to a bit lower level... If anyone
has a "tested" (or documented) answer that would be appreciated
though, and safer than me just trying something new.

Make sure there are no outstanding references to the appointment or any of
its subobjects (attachments, etc).

Thanks, in this case it ended up being that I was using PR_RECORD_KEY
by mistake, instead of PR_ENTRYID, to try and delete the item. With
Exchange folders those two keys are very similar, and it slipped past
me in the debugger, until I switched over to a non-exchange folder and
noticed what I thought was the entryid was only 4 bytes long =)
