I USE TO HAVE MAIL SERVER HOSTED FOR US BY AN ISP, WE USE TO ACESS THIS MAIL SERVER USING OUTLOOK EXPRESS WHICH POINTS TO OUR ANALOG X PROXY AS THE MAIL SERVER; WE THEN CONFIGURE EMAIL ALIASES ON THE ANALOG X PROXY.
MY PROBLEM IS THAT I NOW HAVE A CORPORATE MAIL SERVER WHICH IS EXCHANGE 2000 SRV. IT SERVES AS A LOCAL MAIL SERVER ALONE,(I.E ONLY FOR PEOPLE ON OUR LOCAL NETWORK), I THEN INSTALLED MICROSOFT ISA SERVER AS OUR NEW PROXY, BUT WHEN I CONFIGURED MY OUTLOOK FOR MY EXTERNAL EMAIL IT REFUSES TRO CONTACT MY SERVER HOSTED BY MY ISP.
IS THEIR ANYWHERE I HAVE TO CONFIGURE MAIL ALIASES LIKE IN ANALOG XD. OR SHOULD THEIR BE ANY CONFIGURATION POINTING TO MY HOSTED SERVER.
I CAN BROWSE THE NET FROM BEHIND THE ISA SERVER USING INTERNET EXOPLORER.
THANKS

You need to create packet filters on your ISA server to allow POP3 (port 110) and SMTP (port 25) outgoing and incoming in order for your Outlook clients to be able to access an external email server. Hope this helps!

What version of Outlook are you using? What kind of an error message do you get when you try to connect? I'm assuming that you have an email account set up for your local server. Have you double-checked the account setups on your Outlook clients? You should also have a separate Internet email service set up with your pop3 server identified. Depending upon your version of Outlook, this is a little different, so knowing that would help. The exact error message might also help point us in the right direction, also. Do you have any additional routers between the local network and the Internet? Waiting for your responses . . .

hi ,
thanks for ur help so far. but i figured out the problem. i did not set my gateway address and the dns address in the network properties (for the clients). i did that and everything worked.
