MailMessage saves to file and changes the maildate to currentdate

Hello

in my example code opened MSG-file in MapiMessage and then converts to MailMessage.
Save the MailMessage to a newFilename.
Open newFilename in Outlook and the maildate is changed to currentdate.

It works korret if I use Aspose.Email version 6.5.

var mapiMessage = MapiMessage.FromFile(msgFilename);
using (MemoryStream stream = new MemoryStream())
{
mapiMessage.Save(stream);
stream.Seek(0, SeekOrigin.Begin);
var msg = MailMessage.Load(stream, new MsgLoadOptions());
msg.Save(newFilename, SaveOptions.DefaultMsgUnicode);
}

Thanks
Zhentao

Welcome back, @zhentaosong!
Thank you for the issue description and code snippet. Could you also share the MSG file for investigating the problem, please?

You can test with any MSG-file.

@zhentaosong,
I have checked your code snippet with Aspose.Email 21.1. I found no problems. Please, share more details for the issue:

  • specify changed properties of MapiMessage object or send screenshots
  • specify the version of Aspose.Email library that has the problem

I build my code snippet in the AsposeEmailTest Console Application.
You get the result in the PNG-files, compare the maildate in NewMailFile with OrgMailFile.AsposeEmailTest.zip (4.4 MB)

@zhentaosong,
Thank you for the additional details. I have reproduced the problem and got the same results. I have logged the issue in our tracking system with ID EMAILNET-40096. Our development team will investigate it. You will be notified when it fixed.

We have investigated the issue. Thank you for your patience. To keep original dates, you shoud use PreserveOriginalDates option as below:

var msg = MailMessage.Load(stream, new MsgLoadOptions());
MsgSaveOptions options = SaveOptions.DefaultMsgUnicode;
options.PreserveOriginalDates = true;
msg.Save(dataPath + "NewMsgFile.msg", options);
