I'm copying outlook items from source pst to destination pst. Not all of them but some based on their entryId's.<br/> I have discovered a problem when trying to copy AppointmentItems in Deleted Items folder in the source Pst.<br/> I issue: object obj = appointmentItem.Copy() and then inspect obj for the type. It turns out obj is not AppointmentItem  but MailItem. Also I find the copy being created in Drafts folder in the source pst.<br/> <br/> Would anybody have an idea why Copy method invoked on AppointmentItem returns MailItem? This is really weird and unexplainable to me. Tried googling for more than a day and couldn't find any article adressing my problem.<br/> Thanks<br/> <br/>© 2009 Microsoft Corporation.

Yes , know that copied MailItem contains my AppointmentItem attachment. And this is how I left it with an explaination that this must be by design :)<br/> I have also found other item types (ContactItem, TaskItem, JournalItem) behave the same, or similar.<br/> I don't plain to complain about this but out of curiosity what is 'connect.com'? Typing it in the browser redirects me to Sony connect Europe. (Music downloads powered by Sony)<br/>Mon, 13 Jul 2009 07:23:19 Z2009-07-13T07:23:19Z
