Vote for Attachment Options
Attachment Options is an Outlook 2002 COM add-in that provides a user interface for changing which file types are restricted as Level 1 attachments. Level 1 attachments are hidden by Outlook, and cannot be seen, saved or opened from Outlook items. Moving an attachment extension to Level 2 enables the user to see the attachment and to save it to the file system. The attachment saved to the file system can later be opened by the user.
