OL2002: Outlook Stops Responding in the Mso.dll File When You Open a Message That Is Archived with Third-Party Software

This article has been archived. It is offered "as is" and will no longer be updated.
If you right-click a message that only contains an attachments stub and is archived with third-party software, Outlook 2002 may stop responding (crash) in the Mso.dll file.
The problem occurs because the third-party program deletes the attachment properties in the message. This causes the attachment to be inaccessible in the message, and the attachment is then inaccessible to users.
