Allow blocked Attachments in Outlook 2007

Enables users to create a list of attachment file types to demote from Level 1 to Level 2.

The registry key in which users create the list of file types to demote is:

REG_SZ - HKCU\Software\Microsoft\Office\12.0\Outlook\Security\Level1Remove

 In the registry key, users specify the file types (usually two - three letters) to remove from the Level 1 file list, separated with semicolons.
