With the Microsoft Office 2000 SR-1 and XP has been added the possibility to change the security level for the opening of attachments from Microsoft Outlook...
if we had the need to open an attachment blocked by Outlook, you must run the application regedit.exe and select the following key:
[HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security]
edit or create (if doesn't exist) the following value, for example, to enable attachments with extensions *.EXE e *.VBS:
"Level1Remove"="EXE;VBS"
if we do not want to allow that users can modify the list of files that can not be opened, run the application regedit.exe and select the following key:
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\10.0\Outlook]
edit or create (if doesn't exist) the following value:
"DisallowAttachmentCustomization"=dword:1
