SYMPTOMS
In Microsoft Outlook 2000 and in earlier versions, if the implementation of the IExchExtAttachedFileEvents::OnWritePattToSzFile method on the client extension returns the S_OK value, Outlook considers the event to have been handled. Additionally, Outlook skips this event and continues to process attachments. Eventually, the implementation of the IExchExtAttachedFileEvents::OnOpenSzFile method on the client extension is called.

In Microsoft Outlook 2002, if any value other than the S_FALSE value is returned, Outlook does not process the attachment. Therefore, the IExchExtAttachedFileEvents::OnOpenSzFile method is never called.



CAUSE
If the return value of a client extension is not equal to S_FALSE when Outlook 2002 processes attachments, Outlook incorrectly changes the return value to E_ABORT. This behavior causes the process to stop.
