SYMPTOMS
If you use Network Address Translation (NAT), you may not receive new e-mail notifications in Outlook 2002.
Back to the topCAUSE
This problem can occur in a NAT environment because Outlook 2002 never receives the UDP (Universal Datagram Packets) that the Microsoft Exchange Server sends, and you cannot route the UDP packets to a computer that is running Outlook 2002.
The computer that is running Outlook 2002 returns to polling the Exchange Server for new e-mail messages by using the Remote Procedure Call (RPC) to work around this problem. However, a logic error exists with the Exchange Server and it does not reply to the polling request.

MORE INFORMATION
Outlook 2002 uses both UDP and polling to notify you of new e-mail messages.
With UDP, Outlook 2002 sends the server the client's Internet Protocol (IP) address and notifies the server to send the UDP when there are e-mail messages waiting on the server.
The polling mechanism occurs when Outlook 2002 starts a thread that requests information from the server every 60 seconds with the RPC, by default, for any outstanding e-mail messages.
The default preference for e-mail notification in Outlook 2002 is UDP, and if that fails, then it uses polling. The previously mentioned registry value defines whether or not to use polling as the default for new e-mail notification. The value of 1 indicates that polling is used as the default by Outlook 2002 and that UDP will not be used. The default polling time is 60 seconds and is set at the Exchange Server.
