How to catch an exception in Outlook Object in C# code if Outlook.MailItem.Send() fails due to invalid recipients

The code below can fail due to a lot of causes, e.g., invalid recipients list or nonexistent recipients. For these problems the sender of the mail will get non-delivered report to his inbox.

What I want to achieve is, if the sent email fails because of improper recipient id, then I should intercept the Exception at Catch branch.

try
{
    Outlook.MailItem mail = OutLookInstance.CreateItem(Outlook.OlItemType.olMailItem);
    mail.Subject = "Send to TAM";
    mail.Recipients.Add("[email protected]");
    mail.Body = "Business Alert mail";
    mail.Display(false);
    mail.OriginatorDeliveryReportRequested = true;
    mail.Send();
}
catch(Exception ex)
{
}

The above code is supposed to do that, but it does not throw any exception if the delivery fails.

How to achieve this using Outlook, please let me know?

You need to use the Resolve or ResolveAll methods of the Recipient or Recipients class to resolve a Recipient object against the Address Book.

You can find a sample code in C# and VB.NET in the How To: Create and send an Outlook message programmatically article.
