Had some odd problems after an update failed to apply correctly to my exhcange/ad server. After reboot we are no longer able to access OWA except via the loopback (ie https://localhost/owa
). Cannot access OWA using FQDN, hostname or Static IP address.
Also, Outlook 2010 clients cannot change their Out of Office messages. They receive the error: "Your automatic reply settings cannot be displayed because the server is unavailable..."
In IIS manager > Default Website > SSL Settings. If I uncheck Require SSL I am able to access OWA using FQDN, etc. but only via http, not https, but this does not resolve the Out of Office issue
