Programmatically encrypt Outlook email using Inspector

Question

I\'m using C# with Outlook Object Model (Redemption is not an option for me due to licensing) and I\'m having difficulty programmatically encrypting an email message before send

Answer 1

Figured it out by trial and error. The main problem seemed to be that I was using the Inspector before I had displayed the MailItem. Adding the call to Display at the beginning solved it. For anyone interested, here is the code that worked for me:

private static void addOutlookEncryption(ref Outlook.MailItem mItem) {
        CommandBarButton encryptBtn;
        mItem.Display(false);
        encryptBtn = mItem.GetInspector.CommandBars.FindControl(MsoControlType.msoControlButton, 718, Type.Missing, Type.Missing) as CommandBarButton;
        if (encryptBtn == null) {
            //if it's null, then add the encryption button
            encryptBtn = (CommandBarButton)mItem.GetInspector.CommandBars["Standard"].Controls.Add(Type.Missing, 718, Type.Missing, Type.Missing, true);
        }
        if (encryptBtn.Enabled) {
            if (encryptBtn.State == MsoButtonState.msoButtonUp) {
                encryptBtn.Execute();
            }
        }
        mItem.Close(Outlook.OlInspectorClose.olDiscard);
    }
