HowTo: Unblock restricted file attachments in Microsoft Outlook 2007


If you want (REALLY WANT 🙂 to change the Outlook file attachments security levels (i.e. to read e .exe file attached to a received email), and you know how to use the regedit.exe tool, you can follow the procedure below:

  • Start…Run…"regedit"
  • Go to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security
  • Create a new string value called Level1Remove
  • Enter in the file extensions you want to use, such as .exe or .bat
  • You can have multiple file types separated by a semicolon like this: ".exe;.com"
  • Close and open outlook.

To avoid risks, I suggest to keep the string "Level1Remove" in the registry ONLY for the strict necessary.

    thanks, great tip. After reading through Microsoft´s lengthy explanation why they control what is your right to receive and there is no option in Outlook to configure this, this solved the problem immediatley. THANKS !
