Redirect has been working fine to when users connect to http://owa.company.com they get redirected to a log in page at https://owa.company.com/owa. It's just using the redirect setting in IIS. Then today I created a new ssl certificate and replaced the old one on this Exchange server. Now, I can connect directly to https://owa.company.com/owa just fine and it shows it is using the new certificate, however if I go to http://owa.company.com then I get a 403 http error.
It does work if I go to https://owa.company.com, then it will still redirect to the /owa site, but if I use plain http, then I get the errror.
I'm stumped!! I've tried unchecking the redirect setting, restarting IIS and re-enabling the redirect setting, which did no good. Everything else I've found with googling either has no solution or just gives instructions for enabling the redirect setting.
Again: this was working fine until I renewed the ssl certificate.
