MSG saving problem

When I save my new mail message the from section of email contain this :


and in the top of my email I have a message that say :

Internet message - sender and content cannot be verified

Anyone know what cause this problem and if yes how can I resolve the problem?


Hi Francois,

We are looking into this issue as well and will get back to you on this soon.

Hi Francois,

Could you please share some of your code and the eml file that you use to save to a msg file?

It will help us to find out the root.


There is my code example. What I try to do is to split email that have X attachment in X email with one attachment. I will send you my mail message at your email address.

Aspose.Network.License license = new Aspose.Network.License();

license.SetLicense(File.Open(@"C:\Aspose.Network.lic", FileMode.Open));

MapiMessage msg = MapiMessage.FromFile(@"C:\\Test 2 Attachment.msg");

int counter = 1;

foreach (MapiAttachment att in msg.Attachments)


// outlook msg attachments

string name = String.Empty;

MemoryStream memStream = new MemoryStream();

if (att.ObjectData != null && att.ObjectData.IsOutlookMessage)


MailMessage nestedAtt = MailMessage.Load(new MemoryStream(att.ObjectData.Data),MessageFormat.Msg);

name = nestedAtt.Subject + ".msg";

nestedAtt.Save(memStream, MessageFormat.Msg);


// other attachments



name = att.FileName;

memStream = new MemoryStream(att.BinaryData);


MailMessage mail2 = MailMessage.Load(@"C:\\Test 2 Attachment.msg", MessageFormat.Msg);

mail2.AddAttachment(new Attachment(memStream,name));

mail2.Save(@"C:\Temp\" + counter.ToString() + ".msg", MessageFormat.Msg);



Was a solution ever found to this issue? I am having the same problem.


We are still working on this issue and will post here as soon as any update is available. Thanks for the patience.
