which will notify you about birthday for someone or you want to send 
messages to "mailing list". So you want to naviagte thru list of defined

  outlook := CreateOleObject('Outlook.Application'); 
  NameSpace := outlook.GetNameSpace('MAPI'); 
  Contacts := NameSpace.GetDefaultFolder(olFolderContacts); 
  for i := 1 to Contacts.Items.Count do 
  begin
