My experience with the Export script was less than exemplary. The initial dialog is lacking in the common sense user interface feature of a "Cancel" button. Subsequent dialogs were terse and unexplained adequately in the supplied documentation. Ultimately the script failed with the message "The variable "theFile" is not defined." and then a subsequent: "Could not save changes to the script "Export Messages" because the script's stack overflowed." Overall a less than useful result.
