DTOO131 - Word - Trust Bar Notifications for unsigned application add-ins must be blocked.

Information

If an application is configured to require 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 informing users about the unsigned add-in.

Solution

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Word 2010 -> Word Options -> Security -> Trust Center 'Disable Trust Bar Notification for unsigned application add-ins and block them' to 'Enabled'.
