Is ther some kind of add on for Outlook or a product of some sort to flash users over the LAN? MSN messenger using Instant Messaging on the Exchange server is alright but, I am looking for something simpler that just flashes users so that if they are on the phone a message can be sent to them on top of all their applications to notify them of an important phone call. We don't need the full functionality of MSN Messenger and I don't like the fact that they can connect to the internet such as with a passport. Thank You, Amy
