We still got a problem with conversion of mail messages. With the code below we try to convert a msg formatted mail to RFC 822 format and back to msg format. Now the code which works with Aspose.Network 4.6.0.1 doesn't work any more with version 4.7.0.8. The code fails at the underlined line with the following error description. The error occurs with any msg formatted mail on 32 bit and 64 bit windows platforms.
Best Regards
