DTOO505 - Scripted Window Security must be enforced in PowerPoint Viewer.

Information

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.

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Microsoft Office 2016 (Machine) -> Security Settings -> IE Security 'Scripted Window Security Restrictions' to 'Enabled' and place a check in he 'pptview.exe' check box.
