We are using Aspose.Email version 5.8.0.0. We have built a way for a user to browse to his Exchange mailbox, choose a folder, choose an email, and save the email as a .msg file in the case he is working in.
If the user chooses an email from his Sent Items folder, the resultant file has no “To:” recipient. See the attached message file (renamed .txt to allow attachment). We are simply using FetchMessage to get a MailMessage object back.
