Information
This policy setting controls whether the specified Office application notifies users when unsigned application add-ins are loaded or silently disable such add-ins without notification.
Note: For this policy to apply the
Require that application add-ins are signed by Trusted Publisher
policy setting needs to be enabled. This will prevent users from changing the
Disable Trust Bar Notification for Unsigned Application Add-ins and Block Them
policy setting.
The recommended state for this setting is: Enabled
Allowing unsigned application add-ins could cause the application to load dangerous add-ins and as a result, malicious code could become active on user computer and the network.
Solution
To establish the recommended state via configuration profiles, set the following Settings Catalog path to Enabled
Microsoft Access 2016\Application Settings\Security\Trust Center\Disable Trust Bar Notification for unsigned application add-ins and block them
Impact:
If an application is configured to require that all add-ins be signed by a trusted publisher, any unsigned add-ins the application loads will be disabled, and the application will display the Trust Bar at the top of the active window. The Trust Bar contains a message that informs users about the unsigned add-in.
