Hi, I am trying to setup ISA to allow POP3 and POP3S through to my Internal Exchange server. I already have published OWA and ActiveSync etc. which is all working fine. I added another Mail rule to allow POP3 and POP3S, I can see the requests hitting the ISA server and it says it is forwarding to the correct IP of my exchange server but nothing occurs. It works fine on the internal network so I believe the configuration in ISA may be incorrect. I am using ISA 2006, anyone set this up previously or has any ideas? Thanks in advance.

Hi, Have a look into these article they might help & are u able to telnet for external IP(public IP) on 110 & 995 ports: http://technet.microsoft.com/en-us/library/bb310788(EXCHG.80).aspx http://exchangeserverinfo.com/2008/01/24/publishing-exchange-2007-server-with-isa-server-2006--part-1accessing-owa-externally-through-isa-2006-firewall.aspxRipu Daman Mina | MCSE 2003 & MCSA Messaging

Hi, Everything is working fine with OWA. The problem is with POP3 & POP3S - I can telnet direct to these ports on my internal network, when I try and telnet to the IP of the ISA box on these ports externally, I get nothing, although I get the log hitting the ISA server but for some reason it isn't forwarding the request? Maybe it's more of an ISA question than an Exchange one, I may repeat the question over there. Wanted to find out if anyone was doing this successfully that is all.

Hi Tabmow, This is an ISA issue more than Exchange, I would like to suggest you write the post in our Forefront forum: http://social.technet.microsoft.com/Forums/en-us/category/forefront Thanks, Elvis
