2.3.24.2 (L1) Ensure 'Block opening of pre-release versions of file formats new to PowerPoint 2016 through the Compatibility Pack for Office 2016 and PowerPoint 2016 Converter' is set to 'Enabled'
Information
This policy setting controls whether users with the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2016 File Formats installed can open Office Open XML files saved with pre-release versions of PowerPoint 2016. PowerPoint Open XML files usually have the following extensions: .pptx, .pptm, .potx, .potm, .ppsx, .ppsm, .ppam, .thmx, .xml.The recommended state for this setting is: Enabled
The Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats enables users of Microsoft PowerPoint 2000, PowerPoint 2002, and Office PowerPoint 2003 to open files saved in the Office Open XML format used by PowerPoint. PowerPoint Open XML files usually have the following extensions:
- .pptx
- .pptm
- .potx
- .potm
- .ppsx
- .ppsm
- .ppam
- .thmx
- .xml
By default, the Compatibility Pack does not open files that were saved in pre-release versions of the new Office Open XML format, which underwent some minor changes prior to the final release of PowerPoint. If this configuration is changed through a registry modification or by some other mechanism, users with the Compatibility Pack installed can open files saved by some pre-release versions of PowerPoint, but not by others, which can lead to inconsistent file opening functionality.
Solution
To establish the recommended state via configuration profiles, set the following Settings Catalog path to Enabled :Microsoft Office 2016\Office 2016 Converters\Block opening of pre-release versions of file formats new to PowerPoint 2016 through the Compatibility Pack for Office 2016 and PowerPoint 2016 Converter
Impact:
Enabling this setting enforces the default configuration and is therefore unlikely to cause usability issues for most users.
NOTE: See Plan block file format settings in the Office Resource Kit for more information about using policy to manage and enforce file format requirements. Also, see the 'File Block Technology' section in Chapter 4 of the Microsoft Office Security Guide for information about the Microsoft Office Isolated Conversion Environment (MOICE), which provides another method.
NOTE#2: When enabling this policy the following setting is also set to Enabled :
Microsoft PowerPoint 2016\PowerPoint Options\Security\Trust Center\File Block Settings\PowerPoint beta converters
Both PowerPoint beta converters and the setting in this recommendation share the same registry key and value, so there is no adverse impact from this.
