title: (VBA Outlook) Prompt a message box when sending blanket mail
body: <p>i am wondering if you can all help me, i recently accidentally sent out a blanket email using the To field instead of BCC to about 800 customers.</p>
  
  <p>Is there any way in outlook that it could detect the number of email addresses in the To, CC fields and if more than 5, prompt a message box saying, are you sure?</p>
  
  <p>I suspect VBA</p>
  
  <p>Thanks</p>
