Also, what kind of equipment do you have? A Cisco PIX firewall?

We also started experiencing a similar issue.... from OWA users
can access email... internally they can access email.... externally they get an
error indicating the Exchange server is not available....

Having an odd issue with that myself.
We have DSL service with multiple IP addresses assigned
to it. One IP
address is assigned to our Exchange 2000 server, one of
the IP addresses is
assigned to a Netopia router which then provides NAT
addressing to our users
in the building. With that said, any computer that is
either receving a NAT
address from the Netopia or any computer with a
routable IP in the same
subnet as the Exchange server can retrieve email from
Exchange 2000 with no
problem. However, any computer outside our building
cannot connect to our
Exchange server via IMAP, but can via OWA. DNS queries
against Exchange
from outside the building work fine. Any ideas? It's
almost as if our DSL
modem suddenly decided to start filtering, but it's a
standard SpeedStream
modem provided by SBC (PacBell).
An interesting twist... from outside of our building,
if you establish a VPN
connection with our Netopia router, you can access
Exchange via Outlook
(IMAP). All machines connecting via POP3 from outside
our building receive
their email as well (vpn or not). Kinda getting me
nutty!
Thanks all!

through the Internet using Outlook? Thanks in advance
