So long as OWA is running fine internally then you are good to go.

That sounds the right approach, but I don't know your firewall setup
(and don't want to :-)  ).

Bear in mind that:

1) You are opening port 80 on your exchange server to the world, so you
are open to any iis vulnerability that may subsequently be released.
Keep your server patched! Remember code Red!

2) All traffic, if just using HTTP is not encrypted

3) if you are opening port 80 then they will also be able to do
http://youripaddress/exchange and run OWA from anywhere (see note 2)

4) You need to look at the security implications before doing this. If
your people can get to it from anywhere, then I can too and I'm nicer
than some people :-) Hackers just care that there is a port open and
will run bots against it for fun or money or pain (yours)

Dean,

Thanks a ton! At least I know I'm going in the right direction!

I am running Exchange 2k3.. So I don't have to do anything to make the 
folder accessible via the internet? I think that might be what was 
causing my confusion. I was looking for something to change, or 
something do to, to  set it up.

The network that Exchange is hosted on, does not host any websites at 
all.. It's purely for internal usage. So what I'm thinking I'll do, is
this.

I'll forward all incoming port 80 requests via the firewall to the 
server running Exchange, and into that folder.. That's the only thing 
that would be accessible from the web on our internal network.

Then on the website (Which is hosted externally).. I can just do a php 
include to the IP address of the network.. Might just work...??

For authentication purposes.. When someone hits that public folder from 
the internet. Will they be prompted for login credentials? Cal's aren't 
an issue here.. As this will only be used rarely, when someone is out of

the office..

Thanks for the push in the right direction.

Thanks
David
