Outlook security prompt auto approval

I'm writing a function that will allow users to import their e-mails from outlook in to corporate storage. But I've encounter a problem with security promt, and since we still have clients with office 2003 we can't disable it.

I'm trying to autoclick it with this code:

    [DllImport("User32.dll")]
    public static extern Int32 FindWindow(String lpClassName, String lpWindowName);

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern int SendMessage(int hWnd, int msg, int wParam, IntPtr lParam);

    [DllImport("user32.dll", SetLastError = true)]
    public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle);


    private const int WM_LBUTTONDOWN = 0x201;
    private const int WM_LBUTTONUP = 0x0202;

    private void button1_Click(object sender, EventArgs e)
    {
        int hwnd = 0;
        IntPtr hwndChild = IntPtr.Zero;
        while (true)
        {
            hwnd = FindWindow(null, "Microsoft Outlook");
            if (hwnd != 0)
            {
                hwndChild = FindWindowEx((IntPtr)hwnd, IntPtr.Zero, "Button", "Yes");
                if (hwndChild != IntPtr.Zero)
                {
                    SendMessage((int)hwndChild, WM_LBUTTONDOWN, 0, IntPtr.Zero);
                    SendMessage((int)hwndChild, WM_LBUTTONUP, 0, IntPtr.Zero);
                }
                else
                {
                    //...
                }
            }
            else
            {
                //...
            }
            hwnd = 0;
        }
    }

But when I'm trying to use that code I've encounter unexpected problem. Security promt will only disappear only when I'm actually performing mouse click no matter where even on some empty screen space. What is wrong with it?

Try out MAPILab's Advanced Security for Outlook. Should also work for Outlook 2003. This will let you give a permanent access for your application - a pop-up window will show only the first time you access Outlook items: http://www.mapilab.com/outlook/security/

Advanced Security will have to be installed on each machine you run your app. It's free for noncommercial and commercial use.

You should try using SendKeys and send Y for Yes.
