How to Delete some item from outlook by code in c++

Hi,

I don't know if this is the right forum to ask this question - but i did nto
find any better forum in code project.

I writing code in C++ and i m using com to contol the microsoft outlook.
I try to delete some mail or some appointment with some specific subject or
with some specific body or data from outlook.

But i did not find any good way to do it beside scan all the mail/appointment in the Outlook::olFolderABC
( ABC is mail folder - like inbox/ outbox / olFolderCalendar) and compare with the data that i looking for -and if they are equals then Delete the mail/appointment item.

So i need some "smart" way to find the right item checking each item ..
because scan all the appointment can be a lot of work.

Thanks in advance
