How to save MailMessage object to disk as *.eml or *.msg file

Note that I get when open the .msg file:
Cannot open file: path. The file may not exist, you may not have permission to open it, or it may open in another program. Right-click the folder that contains the file, and then click Properties check your permisstions for the folder.
Thank all.

How exactly are you creating the MSG file? It is completely different from an EML file - see https://stackoverflow.com/questions/16229591/difference-between-a-msg-file-and-a-eml-file/16230261#16230261

MSG file format is a binary IStorage file, and its format is documented. You can parse your EML (MIME) file and copy one property at a time to a programmatically created MSG file.

If using Redemption is an option (I am its author), you can use Session.CreateMessageFromMsgFile to create a new MSG file and RDOMail.Import method to import your existing EML file.

  set Session = CreateObject("Redemption.RDOSession")
  set Msg = Session.CreateMessageFromMsgFile("c:\temp\test.msg")
  Msg.Sent = true '//since Import does not copy this property
  Msg.Import("c:\temp\test.eml", 1024) ' //1024 is olRfc822
  Msg.Save

In Interop Outlook, this is how to locally save a mail as .msg.

mailItem.SaveAs(@"c:\path\to\save\mail.msg", Outlook.OlSaveAsType.olMSG);
