DTOO124 - Outlook - Scripted Window Security must be enforced.
Malicious websites often try to confuse or trick users into giving a site permission to perform an action allowing the site to take control of the users' computers in some manner. Disabling or not configuring this setting allows unknown websites to: -Create browser windows appearing to be from the local operating system. -Draw active windows displaying outside of the viewable areas of the screen capturing keyboard input. -Overlay parent windows with their own browser windows to hide important system information, choices or prompts.
Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2010 (Machine) -> Security Settings -> IE Security 'Scripted Window Security Restrictions' to 'Enabled' and 'outlook.exe' is checked.
