Attachment Options 

Attachment Options is a COM add-in for Microsoft® Outlook® 2000 SP3 or higher, Outlook 2002, and Outlook 2003 or Outlook 2007 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.

To open the Attachment Options property page select the Tools menu, then select Options and go to the Attachment Security & Options  tab. Move any file extensions from the Level 1 list to the Level 2 list, or from the Level 2 list to the Level 1 list as desired. Files are moved from the Level 1 list to the Level 2 list by selecting file extensions and clicking the Move or Move All buttons. Files are moved from the Level 2 list to the Level 1 list by selecting file extensions and clicking the Remove or Remove All buttons.

Attachment Options also provides a check box to enable reading all e-mail as Plain Text, avoiding HTML e-mail virus and malware exploits, for Outlook 2002, 2003 and 2007. The reading e-mail as Plain Text feature is not available for Outlook 2000.

Exit and re-start Outlook to have changes made using Attachment Options take effect.

Note Attachment Options is for Outlook 2000 SP3 or higher, Outlook 2002,  Outlook 2003 and Outlook 2007 only.
