User is trying to access email thru Outlook 2000.
Whenever he tries to open Outlook he receives message
that exchange server is offline, Unable to open mailbox,
etc. The problem is resolved by turning off the WinXP
Internet Connection Firewall. How can firewall be
configured to allow access to exchange server? I have
tried configuring the firewall to allow connection to the
correct IP address of the mail server for all of IMAP3
(TCP port 200), IMAP4 (TCP port 143), SMTP (TCP port 25),
POP3 (TCP port 110), without success.
