Title

Enable Warning Bar settings for VBA macros contained in Access Files. (Cat II impact)

Discussion

By default, when users open files in the specified applications that contain VBA macros, the applications open the files with the macros disabled and display the Trust Bar with a warning that macros are present and have been disabled. Users can inspect and edit the files if appropriate, but cannot use any disabled functionality until they enable it by clicking Options on the Trust Bar and selecting the appropriate action. If users enable dangerous macros, it could affect their computers or cause sensitive information to be compromised.
