In a Microsoft Exchange Server 2007 environment, you use a Collaboration Data Objects (CDO) application that calls the GetAssociatedAppointment method to accept meeting requests. However, if a meeting request includes an embedded message as an attachment, the attachment is corrupt and inaccessible.
