(I feel a bit silly asking this question, as I should have documented better...however, I am under a time constraint!)
We had OWA running with our old (now dead) server. It worked well, but we had to do something a little unique.
Since we had an HTTP app running on another server on the network that needed to be accessed from the Internet (and the HTTP rule on the firewall routed to there), we setup our firewall to route HTTPS to the Exchange server.
Then, when people went to https://webmail.oursite.com/exchange
, they got the usual 'You are about to view connections over a secure connection...' warning, we just hit 'OK' and moved on.
Our server went 'boom' last week, and I cannot remember how we set this up. The IP of the server is the same, so we didn't have to change any settings on our firewall.
I can access the webmail internally no problem.
We get the error message 'You are not authorized to view this page' when accessing remotely.
I am assuming I need to turn something on on the SBS server, but I can't remember what I did two years ago.
Is it because I do not have a certificate installed?
