In a Microsoft Exchange Server 2003 environment, you have a Collaboration Data Objects (CDO) 1.21 application that is used to manage the calendar items. When you use Microsoft Office Outlook to forward a meeting request that was responded to by the CDO application, the "To" field is populated with the original recipients of the meeting request, and the "Subject" field is not prefixed with the letters "FW".
This problem occurs because the Respond method in CDO 1.21 does not clear the MSGFLAG_UNSENT flag from the PR_MESSAGE_FLAGS property on the associated appointment. This causes Outlook to treat the appointment as an unsent message.
