Last week I had OWA and Exchange fully set up. I could access it via https://mail.alden-hebron.org/owa
(please dont laugh if you get to it - I need to buy a security certificate) Anyways sometime over the weekend something happened and now we can't get to it externally. Nothing was really changed in the firewall except one small port 80 setting but it had nothing to do with port 80 for the wan to the lan ip of the exchange server. What else could cause this? Thanks!
