When new mail arrives the Exchange Server sends a UDP packet to the client which forces the client to refresh its view. When the clients need to manually refresh this generally means there is something like a firewall or Proxy client, etc that is not allowing the UDP packet to reach the client machines. I would check your network configuration to see where this could be happening as it sounds like something has changed as it worked fine earlier. Are the clients and Exchange server on the same network segment, etc...

Early this year, it works ok..when someone sends an email, the recipent will receive it automatically without having to click send/receive button. But these few months, the users will have to click send/receive button or else they will not receive the mail. I think my Exch has a problem. Restarting the server is just a temporary measures..a few weeks later the problem will starts again.In fact after restarting it, receving email will not be not as fast as it used to be but not as slow as the user complaints. Is there a properties in Exch that I have to refresh or adjust so that the user can receive email automatically again? appreciate the feedbacks.. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: jeff.horton@xxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
