I have some plugin for Outlook that among other things save email messages to HDD.
I save message like this:
mail.SaveAs("C:\temp\mail001.msg", Microsoft.Office.Interop.Outlook.OlSaveAsType.olMSG);
Now when mail is stored to hdd some system windows properties are not saved, like From address, To address, Has attachments etc.
As you can see on image these columns in explorer are empty.
I wonder is there any way to fill System.Message properties in msg file that is stored to hdd ?
