Details

When an Office Open XML document is protected with a password and saved, any metadata associated with the document is encrypted along with the rest of the document’s contents. If this configuration is changed, potentially sensitive information such as the document author and hyperlink references could be exposed to unauthorized people.

Solution

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2013 -> Security Settings ‘Protect document metadata for password protected files’ to ‘Enabled’.
