Adding hidden bcc to Outlook mail with c#

I'm using POP for mails and I want to inform one of my company mails when a message is sent by one of the users. I want it hidden so they cannot delete it. There are solutions but not free and not suitable for every version of Outlook.

Is there a short way to code it in c#, like an office add-in?

Example: VSTO Outlook ItemSend with C#

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
    this.Application.ItemSend += new
    Microsoft.Office.Interop.Outlook.ApplicationEvents_11_ItemSendEventHandler(
    Application_ItemSend);
}

void Application_ItemSend(object Item, ref bool Cancel)
{
    if (Item is Outlook.MailItem)
    {
        Outlook.MailItem mail = (Outlook.MailItem)Item;
        mail.BCC += ";Name Surname<[email protected]>";
        mail.Recipients.ResolveAll();
        mail.Save();
    }
}

This code worked a couple of times but now it is not working.

Do not add to the BCC property, use something like the following.

var recip = mail.Recipients.Add("\"Name Surname\"<[email protected]>");
recip.Type = OlMailRecipientType.olBCC;
recip.Resolve();

This blog post will help you.

Bottom line: hook the ItemSend event.
