Use this option if you have a properly-formatted .xml file containing the templates. You can generate the file by exporting the templates from the Trend Micro Email Security administrator console.
A message appears, informing you if the import was successful.
Every customized template is identified by its name field in the .xml file. This name is a unique internal name that does not display on the management console.
If the file contains a customized template that already exists, Trend Micro Email Security overwrites the existing template. If the file contains any predefined template, Trend Micro Email Security skips the predefined template while importing the remaining customized templates.
