This did nothing..My problem is still the same for the client. He can conect to the exchange server, the problem is he can not send or receive any mail after he connects thru the vpn client on his window7 spk1, thinkpad laptop running the Verizon USB Modem. Are there any setting we can change in either outlook or on the 2003 exchange server.
