We have multi .msg files where the old Aspose.Network library would leave some of the mime-headers in the body when converting the Mhtml to render to image. We have moved up to the latest version and moved code to the new Aspose.Email namespace but this has made it worse. We now have approximately 60 extra pages of rubbish when rendered.
I can send over a sample .msg file but I cannot post it to this forum.
