VBA: OUTLOOK 2010 Prefix Subject [Secure]

[nothlit]

Code: [Select]

Sub HelloWorldMessage()
    Dim msg As Outlook.MailItem
    Set msg = Application.CreateItem(olMailItem)
    msg.Subject = "Hello World!"
    msg.Display
    Set msg = Nothing
End Sub
So far the best example online I have been able to find is the above one. What I want though is on the currently open email message add [Secure] into the subject. This would be email replies or forwards more then anything ... the above is only for new emails. I have searched for the right VBA trigger but am not finding anything.
