title: Change "Item.To" value in outlook when sending a message using VBA
body: <p>I'm trying to change the email address in Send To field in Outlook when the user press send button. for example , if the current <code>Item.To</code> value = <code>'aaa@example.com'</code> it becomes <code>'bbb@example.com'</code>.</p>
  
  <p>I can change the subject , but failed with Item.To ( is it security issue ? ) :</p>
  
  <pre><code>Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
  
     If Item.Class &lt;&gt; olMail Then Exit Sub
  
     Item.To = "bbb@example.com"  ' Nope , It does not work
     Item.Subject = "New Subject" ' It works
  
  End Sub
  </code></pre>
  
  <p>Thanks</p>
