Need to suppress Outlook message on msg.Send()




I am trying to send a meeting programmatically using following code:

// Create the Outlook application.
Outlook.Application oApp = new Outlook.Application();

// Get the NameSpace and Logon information.
Outlook.NameSpace oNS = oApp.GetNamespace("mapi");

// Log on by using a dialog box to choose the profile.
oNS.Logon(Type.Missing, Type.Missing, true, true);

// Create a new appointment item.
Outlook.AppointmentItem oMsg =

// Set the subject.
oMsg.Subject = "Send Using OOM in C#";

// Add a recipient.
Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
Outlook.Recipient oRecip =
(Outlook.Recipient)oRecips.Add("(e-mail address removed)");

// Send.

// Log off.

// Clean up.
oRecip = null;
oRecips = null;
oMsg = null;
oNS = null;
oApp = null;
// Simple error handling.
catch (Exception ex)
Console.WriteLine("{0} Exception caught.", ex);

When the "oMsg.Send()" is called, Outlook pops open a dialog box with
the following message:
"A program is trying to automatically send e-mail on your behalf. Do
you allow this?..."

Since our requirement is to send meeting automatically behind the
scene, we do not want to have this dialog box pop-up everytime we send
a meeting request.

Is there a way to bypass this message box?

Your help would really be appreciated. Thanks a lot.
