Hi I have enabled courtesy email notification when patrons check-in, check-out, advance notice, due and overdue items. Now for existing patrons accounts, it appears it is necessary to modify the patron message preferences for each existing account. New accounts can always inherit the preferences from the patron categories settings. But it is existing accounts where I am looking for a way to update the patron messaging prefereces, either through a script or something.
