Exchange Server 2007: You cannot use an Outlook 2007 client to display or download an attachment when you access a message that includes an inline attachment from Microsoft Exchange Server

SUPPORT SOLUTION:
Consider the following scenario. A MIME-encoded message that includes an inline attachment arrives in Microsoft Exchange Server. You try to access the message from a Microsoft Office Outlook 2007 client. In this scenario, the attachment is hidden, and it is unavailable for download. If you use Microsoft Office Outlook Web Access to view the same message, the inline attachment is still hidden. However, the inline attachment is available for download in Outlook Web Access, and you can click the message and view it..This issue occurs when Exchange Server does not validate whether there is a reference to the inline attachment. If the inline attachment is not referenced, the inline attachment is hidden..Exchange Server 2010

behavior that is mentioned in the “Symptoms” section. If the TreatInlineDispositionAsAttachment option is set to
“true,” the inline attachment that is not referenced is available for
