If you change or add a location make sure that the new location is secured, with only appropriate user permissions to add document/files.If you enable this policy setting, you can specify a trusted location (or folder) from which the 2016 Office application can open the files which run macros without warning.If you disable or do not configure this policy setting, the trusted location is not specified.
