MSG to PDF, set locale for the mail header (from, sent, to, subject...)

Hello guys,

I am working with Aspose Email + Aspose Words (Java) to render a .msg file to a .pdf file. I’m using exaclty the code given by the doc and it works pretty well, the render in PDF looks almost perfect ! However, I have a problem with the “header” of the email which contains the “From, Sent, To, Subject” fields and they are in English and i couldn’t write them in French in the PDF.

It’s the same for the date of sending by the way.

I tried many things like setting the Locale and the CurrentThreadLocale like it’s done here but nothing works:’(

Does anybody have any idea to solve this problem ? Maybe it’s not possible at all ?

Thanks in advance for your help !


Could you please ZIP and attach your input MSG and problematic output MHTML file here for testing? We will investigate the issue and provide you more information on it.

Hi @tahir.manzoor,

Thanks for helping me, you will find attached a zip file containing :

  • An example .msg file
  • The corresponding .mhtml
  • The corresponding .pdf rendering

example msg.zip (93.9 KB)

And also here is my code to generate the PDF file from the .msg InputStream :

public AsposeFileDTO msgToPdf(MultipartFile file) throws Exception {
    Locale.setDefault(new Locale("fr", "FR"));

    try(MailMessage msg = MailMessage.load(file.getInputStream())) {
        ByteArrayOutputStream emlStream = new ByteArrayOutputStream();
        msg.save(emlStream, SaveOptions.getDefaultMhtml());
        Document doc = new Document(new ByteArrayInputStream(emlStream.toByteArray()));

        ByteArrayOutputStream foStream = new ByteArrayOutputStream();
        doc.save(foStream, SaveFormat.PDF);

        String filename = msg.getSubject().replaceAll("[^a-zA-Z]+", " ").trim();
        return new AsposeFileDTO(filename + ".pdf", "application/pdf", foStream.toByteArray());
    catch (Exception e) {
        throw FonctionnelException.format(GedErrorEnum.AUX_500_FILE_CONVERT_ERROR);

Thanks you in advance,
Antoine C.

You can use MhtSaveOptions.FormatTemplates property as shown below to write headers in French:


MailMessage msg = new MailMessage("from@host.com", "to@host.com", "subject", "body");

MhtSaveOptions mhtSaveOptions = new MhtSaveOptions();
mhtSaveOptions.getFormatTemplates().set_Item(MhtTemplateName.DATE_TIME, "dddd d MMMM yyyy HH:mm");
        mhtSaveOptions.getFormatTemplates().get_Item(MhtTemplateName.FROM).replace("From:", "De :"));
        mhtSaveOptions.getFormatTemplates().get_Item(MhtTemplateName.SENT).replace("Sent:", "Envoyé :"));
        mhtSaveOptions.getFormatTemplates().get_Item(MhtTemplateName.TO).replace("To:", "À :"));
        mhtSaveOptions.getFormatTemplates().get_Item(MhtTemplateName.CC).replace("Cc:", "Copie :"));
                .replace("Subject:", "Objet :"));

msg.save("test.mhtml", mhtSaveOptions);
