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 select the check boxes for all installed Office programs.
