I have a SBS 2000 server and use the Exchange portion of it. I want to know how to make OWA availible from the WAN side of the network while keeping it secure. Is there a secure way of doing this. I use A Sonicwall SOHO firewall. Opening the HTTP port 80 would leave a big security hole. Any help is appreciated. Thank You.

You can use OWA over SSL, that's how most companies do it. That secures the usernames and passwords etc.. I'd also suggest installing OWA on seperate server and opening https to it, if possible, rather than opening the port directly to the Exchange server. Keeping a seperate box patched is easier and safer that applying the endless stream of patches to your Exchange server, with the usual reboot. I also consider it more secure.

At work we have set up a FE/BE for OWA talking to an exchage cluster and only publish owa on ssl. This gives us encryted traffic and opens all the options of OWA. And it keeps our audit team happy
