Details

When Microsoft Office files are opened from trusted locations, all the content in the files is enabled and active. Users are not notified about any potential risks that might be contained in the files, such as unsigned macros, ActiveX controls, or links to content on the Internet.

By default, users can specify any location as a trusted location, and a computer can have a combination of user-created, OCT-created, and Group Policy-created trusted locations.

Solution

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2013 -> Security Settings -> Trust Center ‘Allow mix of policy and user locations’ to ‘Disabled’.
