One model for messages and Outlook artifacts

OfficeIMO.Email reads and writes EML/MIME, MSG, OFT, TNEF, mbox, calendar, contact, and Outlook store artifacts through managed .NET APIs. It does not require Outlook, COM, MailKit, MimeKit, MsgKit, or a native storage library.

using OfficeIMO.Email;

EmailDocument message = EmailDocument.Load("message.msg");
Console.WriteLine(message.Subject);
message.Save("message.eml");
