Create a PostItem in the folder, not a MailItem, and use True for the third parameter of UserProperties.Add.

What exactly need to be done to the MailItem for this to work?
I have the following code (C#):
dummyMailItem.UserProperties.Add("Dummy", Outlook.OlUserPropertyType.olText,
true, System.Type.Missing);
dummyMailItem.Subject = "Dummy";
dummyMailItem.Body = "Dummy";
dummyMailItem.To = ";
dummyMailItem.Save();
//dummyMailItem.Delete();
However, the mail item isn't added to the folder, and the user property
isn't added as user propertiy column.
Why not?
