Emailing from C#

Question

When I email using Outlook.Application:

 

Outlook.Application outlookApp = new Outlook.Application();

Outlook._MailItem email = (Outlook._MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);

email.Subject = listView2.SelectedItems[0].ToString() + " Your Store Order Reviewed (TESTING)";

email.To = "[email protected]";

if (Approved)

{

email.CC = "[email protected]";

}

email.HTMLBody = emailBody;

email.Send();

I get this annoying security message from Outlook which I have to press send to sent the email.

How can I get around this?
