Problem loading mhtml from msg

I have a msg file that the Aspose.Network SDK can read, I can see all the properties of the message, however when I save it to mhtml to read in to a Words document (so I can render to iamge) I am told the mhtml is corrupt. If I save the content to a mhtml file on disk it seems to open OK though.

Thanks for your inquiry. Could you please attach the .msg file you are getting problem with and the code you are using? I will check it on my side and provide you more information.
Best regards,
