Information

Document metadata for rights managed Office Open XML files must be protected.

GROUP ID: V-223285
RULE ID: SV-223285r1067544

This policy setting determines whether metadata is encrypted in Office Open XML files that are protected by Information Rights Management (IRM). If this policy setting is enabled, Excel, PowerPoint, and Word encrypt metadata stored in rights-managed Office Open XML files and override any configuration changes on users' computers.

If this policy setting is enabled, Office 2016 applications cannot encrypt metadata in rights-managed Office Open XML files, which can reduce security. If this policy setting is not configured when Information Rights Management (IRM) is used to restrict access to an Office Open XML document, any metadata associated with the document is not encrypted.

Solution

Set the policy value for

User Configuration >> Administrative Templates >> Microsoft Office 2016 >> Security Settings 'Protect document metadata for rights managed Office Open XML Files'

to 'Enabled'.
