External OWA

I have an Exchange 2003 server I can access internally. I cannot access OWA externally. I do have ISA or a front end server. I'm not using a SSL certificate. I want to be able to access OWA externally with the least amount of hassle. Mail is flowing in and out normally to all of the clients. I did not build this server and usually have never experienced this problem before. Oh yeah, POP3 is working. HELP!

You indicate that you have ISA which is a firewall...you need to setup a rule to allow external users access to OWA

EndureKona, What would that rule for ISA with web listener to for OWA look like? Like I stated before I'm running ISA or did you mean IIS? Is there a link to setting that up?

What is the version of ISA you have  2004 or ISA 2006?

I'm sorry I'm NOT running ISA. Sometimes I skip words when I type.

Rick FeeMessaging Engineer - Disaster Recovery EngineerCommented:
Sorry you said "I do have ISA"

What type of firewall do you have?   You have to setup port 80 or 443 forward to your OWA server.

NpatangCommented:
In any kind of firewall there has to be rule for web with port 80 and 443
