@sureshkumarg,

You may please consider trying some code like below on your end.

MapiMessage mapiMessage = MapiMessage.FromFile(@"Microsoft's Home Use Program offers Office 2016.msg");
MailMessageInterpretor mailMessageInterpretor = MailMessageInterpretorFactory.Instance.GetIntepretor(mapiMessage.MessageClass);
MailMessage mailMessage = mailMessageInterpretor.Interpret(mapiMessage);
