Outlook 2010 - Allowing or blocking attachments with Group Policy

Hope this helps,

Hi Samuel,

By "disable the attachment security mode", do you mean you want to disable the Outlook attachment security warning? Would you please provide a screen shot so that we can understand the question more clearly?

If it is the standard Outlook security warning, you may follow these steps to fix it:

1. Press windows key + R to open the run command. Type Regedit and press enter to open the registry editor.

2. Browse to the appropriate key for your version of Outlook. For Outlook 2010:

HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security

3. Add a new String value named Level1Remove.

4. For the value for Level1Remove, enter a semicolon-delimited list of file extensions. For example, entering this: .zip;.mdb;.url; would force you to save Zip file type and unblock Microsoft Access files and Internet shortcuts.
