2.5.10.6.1.4 Ensure 'Do not allow Outlook object model scripts to run for shared folders' is set to 'Enabled'

Information

This policy setting controls whether Outlook executes scripts associated with custom forms or folder home pages for shared folders. If this policy setting is enabled, Outlook cannot execute any scripts associated with shared folders, overriding any configuration changes on users' computers.

The recommended state for this setting is: Enabled.

Rationale:

In Outlook, folders can be associated with custom forms or folder home pages that include scripts that access the Outlook object model. These scripts can add functionality to the folders and items contained within, but dangerous scripts can pose security risks. Outlook does not allow scripts included in custom forms or folder home pages for shared folders to execute. If this configuration is changed, users can inadvertently run dangerous scripts when using shared folders, which can put their computers or data at risk.

Impact:

Enabling this setting enforces the default configuration in Outlook, and therefore is unlikely to cause usability issues for most users.

Solution

To establish the recommended configuration via GP, set the following UI path to Enabled:

User Configuration\Administrative Templates\Microsoft Outlook 2016\Outlook Options\Other\Advanced\Do not allow Outlook object model scripts to run for shared folders

Default Value:

Enabled. (Outlook cannot execute any scripts associated with shared folders.)
