forwrding email and keeping the format

I am using aspose email to forward an email message from exchange. The email is forwarding, but the recipient is receiving the email in text format and not in the original html format.

Is there a way to forward the email and keep it in html format?

I just want to be able to forward the email keeping the original format.

Here is a snippet of code I am using
For example,
private IEWSClient _client;
 _client = EWSClient.GetEWSClient(.....)
var mailMessage = new MailMessage(fromEmailAddress, toSenderEmail, messageSubject, messageBodyPrefix);
_client.Forward(mailMessage, exchangeMessage.asp oseExchangeMessageInfo);

Any help or ideas is much appreciated. Thanks.
