What is MSGReader
MSGReader is a C# .NET 4.6.2, .NET Standard 2.0 and .NET Standard 2.1 assembly to read Outlook MSG and EML (Mime 1.0) files. Almost all common object in Outlook are supported:
- Appointment
- Task
- Contact card
- Sticky note
It supports all body types there are in MSG files, this includes:
- Text
- HTML
- HTML embedded into RTF
- RTF
MSGReader has only a few options to manipulate an MSG file. The only option you have is that you can remove attachments and then save the file to a new one.
If you realy want to write MSG files then see my MsgKit project on GitHub (https://github.com/Sicos1977/MsgKit)
Read properties from an Outlook (msg) message
using (var msg = new MsgReader.Outlook.Storage.Message("d:\\testfile.msg"))
{
var from = msg.Sender;
var sentOn = msg.SentOn;
var recipientsTo = msg.GetEmailRecipients(MsgReader.Outlook.RecipientType.To, false, false);
var recipientsCc = msg.GetEmailRecipients(MsgReader.Outlook.RecipientType.Cc, false, false);
var subject = msg.Subject;
var htmlBody = msg.BodyHtml;
// etc...
}
Detecting charset encoding in MSG files with HTML encapuslated into RTF that use different font set encodings
Most of the times when an HTML body is used in an MSG file this HTML body is encapsulated into RTF. See this link for more info --> https://learn.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-oxrtfex/4f09a809-9910-43f3-a67c-3506b09ca5ac
When an HTML body contains chars that are not in the default extended ASCII range then these chars are encoded. This is normally not a problem when just one language is used. When multiple languages are used then it is quite often that the RTF is not build correctly in a way so that MSGReader can figure out what kind of encoding needs to be used to decode the chars. Because of this MSGReader uses the nuget package UTF.Unknown (https://www.nuget.org/packages/UTF.Unknown/) to try to figure out in what kind of encoding a char is stored. Most of the times this works correctly and because of that a threshold is set to a value of 0.90 so that when the detection level passes this value it will be seen as a valid char.
If you still have bad results you can control this confidence level yourself by using the property CharsetDetectionEncodingConfidenceLevel
in the Reader
or Message
class
/// <summary>
/// When an MSG file contains an RTF file with encapsulated HTML and the RTF
/// uses fonts with different encodings then this levels set the threshold that
/// an encoded string detection levels needs to be before recognizing it as a valid
/// string. When the detection level is lower than this setting then the default RTF
/// encoding is used to decode the encoded char
/// </summary>
/// <remarks>
/// Default this value is set to 0.90, any values lower then 0.70 probably give bad
/// results
/// </remarks>
public float CharsetDetectionEncodingConfidenceLevel { get; set; } = 0.90f;
Read properties from an Outlook (eml) message
var fileInfo = new FileInfo("d:\\testfile.eml");
var eml = MsgReader.Mime.Message.Load(fileInfo);
if (eml.Headers != null)
{
if (eml.Headers.To != null)
{
foreach (var recipient in eml.Headers.To)
{
var to = recipient.Address;
}
}
}
var subject = eml.Headers.Subject;
if (eml.TextBody != null)
{
var textBody = System.Text.Encoding.UTF8.GetString(eml.TextBody.Body);
}
if (eml.HtmlBody != null)
{
var htmlBody = System.Text.Encoding.UTF8.GetString(eml.HtmlBody.Body);
}
// etc...
Delete attachment from an Outlook message
This example deletes the first attachment
var outlook = new Storage.Message(fileName, FileAccess.ReadWrite);
outlook.DeleteAttachment(outlook.Attachments[0]);
outlook.Save("d:\\deleted.msg");

Installing via NuGet
The easiest way to install MSGReader is via NuGet.
In Visual Studio's Package Manager Console, simply enter the following command:
Install-Package MSGReader
Side note
This project can also be used from a COM based language like VB script or VB6. To use it first compile the code and register the com visible assembly with the command:
Regasm.exe /codebase MsgReader.dll
After that you can call it like this:
dim msgreader
set msgreader = createobject("MsgReader.Reader")
msgreader.ExtractToFolderFromCom "the msg file to read", "the folder where to place the extracted files"
