How to send outlook email as non editable

Hello,

I’ve an email stored as .msg. This email is not sent, so when the .msg file is opened, the user can change the content of the mail. I want to forbid this.

Here is the code I tried:

Dim mapiMsg As MapiMessage = MapiMessage.FromMailMessage( “test3.msg”)
mapiMsg.SetMessageFlags(MapiMessageFlags.MSGFLAG_UNMODIFIED)
'Dim ms As MemoryStream = New MemoryStream()
mapiMsg.Save(“test3.msg”)
then i open the test3.msg is non editable as like send item. But one problem is no date display it show none
