Using MailItem::Move in C++

[Martynas Kunigelis]

Hi everyone,

consider this C++ code (Outlook typelib imported with raw_interfaces_only):

-----------------------------------------------------

Outlook::MAPIFolder* pTargetFolder;
Outlook::_MailItem* pMailItem;

....
//
// pTargetFolder and pMailItem are correctly initialized here
//
....

IDispatch* pReturnedItem;

HRESULT hr = pMailItem->Move(pTargetFolder, &pReturnedItem);

-----------------------------------------------------

As far as I understand, pReturnedItem points to a new object that represents
the moved item. I further call QueryInterface() on it to obtain a pointer to
Outlook::_MailItem.

The question is: should I call Release() on the original pMailItem after
Move()?

I would think so, but I'm chasing a weird bug that makes Outlook XP crash on
exit, in InterlockedDecrement in kernel32.dll, called from ole32.dll. I'm
suspicious that InterlockedDecrement is used to decrement the reference
count on a COM object, and that something is getting released one time too
many in my code.

Thanks in advance,
Martynas

Yes, after calling Move() the original message becomes invalid and must be
immediately released.
