Internet Email Problems on SBS 2003 Clients

I have a small LAN with SBS 2003 running Exchange, ISA etc. Email is collected and sent without any problems via Exchange and delivered to each client running Outlook 2003. Web access is configured via ISA, there are no restrictions and the users again have no problems. One user wants to access his personal internet email account via Outlook in addition to his Exchange company account. I have set it up as a normal internet account (on his pc) with the usual Pop3 and SMTP info but get the following error message:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account. account name, Server: 'server name', Protocol: POP3, Server Response: '+OK', Port: 110, Secure(SSL): N0, Error Number: 0x800ccc0f.

My ports are not blocked in ISA, there is no firewall preventing this access and if I log on to the server and configure Outlook in the same way as the client pc, all is fine. None of the workstations will allow this but the server connects happily. I feel as though I am missing some obvious permission here but I just can't find it. The client pcs are running Windows XP Pro.

Any help would be greatly appreciated.

install firewall client or make that user a secure nat client, then in isa server go to Extentions then application filters in HTTP redirector filter select " Send to requested Web Server".

Because web proxy server remove any authentication information from the requests.

install firewall client on the client machine and remove the proxy information from the internet explorer connection tab.

I hope this will work.

Thanks again for the help, we've decided that we don't need the additional ISP email accounts so I don't need to pursue this further. Appreciate the help.
