Changing Outlook’s Macro Security Settings

If you ever have a need to programmatically change Outlook’s macro security settings (or to change it outside of Outlook), you can do so by editing the values of this key in the Windows Registry:




These are the settings in Outlook’s Macro Security dialog and the corresponding values:




No warnings and disable all macros


Warnings for signed macros; all unsigned macros are disabled


Warnings for all macros


No security check for macros (Not recommended)



If you change the value while Outlook is running, the change will be reflected in the dialog but the changes won’t be applied until after you restart Outlook.
