How can I lock the UDP port that Microsoft Exchange Server uses to notify Microsoft Outlook clients that new mail has arrived?
June 30th, 2005 . by AliThe “New mail” notification that Exchange uses operates over a dynamically assigned UDP port that the Outlook client selects when it first connects to the Exchange server. If you need to lock down this port to enable notification through a firewall, you need to make a client-side registry change (this setting is supported only in Outlook 2003).
To do so, create the new DWORD value HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\RPC\FixedUDPPort and set it to the port that the client will listen on for mail notifications.
