Issue in mapiMessage.ToMailMessage API

Aspose.Email Product Family
1

mapiMessage.ToMailMessage loses some of the email text when converting a MapiMessage
to a MailMessage.
As a result when we save this email to a PDF the PDF does not have some of the text included
in the email.

To Repro. run the following code:

            string filePath = @"C:\tmp\Re Catch up over next few weeks - Copy.msg";

            using (var stream = File.OpenRead(filePath))
            {
                MapiMessage mapiMessage = MapiMessage.FromStream(stream);
                MailMessage mailMessage = mapiMessage.ToMailMessage(new MailConversionOptions());

                if (mapiMessage.BodyHtml.Contains("6/21: 10:00-3:00pm PT") &&
                    !mailMessage.HtmlBody.Contains("6/21: 10:00-3:00pm PT"))
                {
                    Console.WriteLine("MapiMessage HTML has more text than MailMessage HTML");
                }
           }

We have tested the sample code provided and it worked fine. Moreover, we have converted mailMessage to PDF as well and the generated PDF is showing complete text. Please have a look on the generated PDFSaveEmailAsPDF_out.pdf (119.8 KB).

For generating PDF, you may follow the code sample given below:

string filePath = @"D:\sample\" + "Re-Catch-up.msg";
            
using (var stream = File.OpenRead(filePath))
{
    MapiMessage mapiMessage = MapiMessage.FromStream(stream);
    MailMessage mailMessage = mapiMessage.ToMailMessage(new MailConversionOptions());

    if (mapiMessage.BodyHtml.Contains("6/21: 10:00-3:00pm PT") &&
        !mailMessage.HtmlBody.Contains("6/21: 10:00-3:00pm PT"))
    {
        Console.WriteLine("MapiMessage HTML has more text than MailMessage HTML");
    }
    else
    {
        MemoryStream ms = new MemoryStream();
        mailMessage.Save(ms, Aspose.Email.SaveOptions.DefaultMhtml);

        // create an instance of LoadOptions and set the LoadFormat to Mhtml
        var loadOptions = new Aspose.Words.LoadOptions();
        loadOptions.LoadFormat = LoadFormat.Mhtml;

        // create an instance of Document and load the MTHML from MemoryStream
        var document = new Aspose.Words.Document(ms, loadOptions);

        // create an instance of HtmlSaveOptions and set the SaveFormat to Html
        var saveOptions = new Aspose.Words.Saving.PdfSaveOptions();
        document.Save(@"D:\sample\" + "SaveEmailAsPDF_out.pdf", saveOptions);
    }
}

Did you change the file I sent you? Any modifications to the msg will make the problem go away.

To further investigate I created a stand-alone Visual Studio 2017 console App
referencing Aspose Email 18.8 and Aspose Words 18.9.
This is the app:
https://www.dropbox.com/s/uo3cbu6y96eswq5/AsposeEmailTest.zip?dl=0

The app includes the repro file and the code below.

When running this app I get the message:
MapiMessage HTML has more text than MailMessage HTML

And the resulting PDF does not include the line:
6/21: 10:00-3:00pm PT

If you want to try the app, you will need to do a nuget restore, as I did not include the packages
to make the app smaller.

I did not include the license in the test app … as I don’t think it matters ( I can repro the problem when using
a license)

This is the full app:

using System;
using System.IO;
using Aspose.Email;
using Aspose.Email.Mapi;

namespace AsposeEmailTest
{
class Program
{
static void Main(string[] args)
{
string filePath = @“Re-Catch-up.msg”;
using (var stream = File.OpenRead(filePath))
{

            MapiMessage mapiMessage = MapiMessage.FromStream(stream);
            MailMessage mailMessage = mapiMessage.ToMailMessage(new MailConversionOptions());

            if (mapiMessage.BodyHtml.Contains("6/21: 10:00-3:00pm PT") &&
                !mailMessage.HtmlBody.Contains("6/21: 10:00-3:00pm PT"))
            {
                Console.WriteLine("MapiMessage HTML has more text than MailMessage HTML");
            }

            MemoryStream ms = new MemoryStream();
            mailMessage.Save(ms, Aspose.Email.SaveOptions.DefaultMhtml);

            // create an instance of LoadOptions and set the LoadFormat to Mhtml
            var loadOptions = new Aspose.Words.LoadOptions();
            loadOptions.LoadFormat = Aspose.Words.LoadFormat.Mhtml;

            // create an instance of Document and load the MTHML from MemoryStream
            var document = new Aspose.Words.Document(ms, loadOptions);

            // create an instance of HtmlSaveOptions and set the SaveFormat to Html
            var saveOptions = new Aspose.Words.Saving.PdfSaveOptions();
            document.Save(filePath + ".pdf", saveOptions);
        }

    }
}

}
