Convert SMIME Outlook Message MSG to MHTML & then MHTML to PDF using Java | Avoid Duplicate Content

AsposeEmailSMimeToPdf.zip (1.4 KB)

When trying to convert SMIME (Signed email) Outlook .MSG file to PDF/A compliant format with Java, the message content gets duplicated in the resulting PDF. Here is the sample code uploaded for reference. Can you please check if this is the issue with the current Aspose email version and is there any fix available for the same ? I am using Aspose.email-20.5, Aspose.pdf-20.6.

Thanks a lot in advance for your feedback and quick support as this is urgent for one of the production issue with the signed email conversion to PDF.

For reference, I followed the below article (for .NET) and prepared the snippet with similar logic in JAVA.


Apparently, there seems no issue in Java code shared by you. I suggest you to please try using latest Aspose.Email for Java 20.9 and Aspose.PDF for Java 20.9 on your end. In case the issue is still reproduced then please share the source MSG file, generated PDF file, intermediate MHT file and snapshot of difference between MSG and output.

Can you please share your email id where I can share the sample email, with generated PDF and intermediate MHT file for your investigation ? Please deal with caution and delete the email after your investigation as this is one of the customer email, but it does not contain any sensitive details as confirmed by business.
