Rebex.Msg 8.0.9797

Rebex MSG - The C# Outlook MSG library for .NET

Rebex MSG is a .NET library for reading, processing, and writing Microsoft Outlook .MSG email message files. It provides access to message subject, bodies (plain text, HTML, RTF), sender, recipients, and attachments through the MsgMessage class, and allows direct manipulation of MAPI properties. For working with EML (MIME) messages and S/MIME, use Rebex.Mail. To send and receive messages, use Rebex.Smtp, Rebex.Imap, Rebex.Pop3, Rebex.Ews, or Rebex.Graph.

Key features

• MSG message API - load, save, create, and manipulate Outlook MSG messages; subject, plain text/HTML/RTF bodies, sender, recipients, attachments
• MAPI properties - list, read, and write MAPI properties by tag, numerical ID, or string name
• MIME and S/MIME - convert between MSG and EML formats; sign, encrypt, and verify messages using X.509 certificates (via Rebex.Mail)

Getting started

Load and inspect a MSG file

// load a message from file
var message = new MsgMessage();
message.Load(@"C:\MyData\sample.msg");

// print some info
Console.WriteLine("Subject: {0}", message.Subject);
Console.WriteLine("From: {0}", message.From);
Console.WriteLine("Body: {0}", message.BodyText);

Create a new MSG message

var message = new MsgMessage();

// set subject and body
message.Subject = "Rebex MSG sample";
message.SetBody("This is plain-text body.", "This is <b>HTML</b> body.", null);

// set sender
message.From = new MsgAddress("alice@example.org", "Alice");

// add recipients
message.To.Add("bob@example.org", "Bob");
message.CC.Add("Joe <joe@example.org>");

// add an attachment
message.Attachments.Add(@"C:\MyData\report.pdf");

// save the message
message.Save(@"C:\MyData\message.msg");

Save to a stream

var message = new MsgMessage();
message.Load(@"C:\MyData\sample.msg");

// save the message into a memory stream
var stream = new MemoryStream();
message.Save(stream);

Work with attachments

var message = new MsgMessage();
message.Load(@"C:\MyData\sample.msg");

// display the list of attachments
foreach (MsgAttachment attachment in message.Attachments)
{
    Console.WriteLine("Attachment: {0} ({1} bytes)",
        attachment.FileName,
        attachment.Data.Length);
}

Access MAPI properties

var message = new MsgMessage();
message.Load(@"C:\MyData\sample.msg");

// get a property value
string subject = message.Properties.GetValue<string>(MsgPropertyTag.Subject);

// set a new property value
message.Properties.SetValue(MsgPropertyTag.Subject, "New subject");

// display all MAPI properties
foreach (MsgProperty prop in message.Properties)
{
    Console.WriteLine("{0}: {1}", prop.Tag, prop.Value);
}
