I have a client running Server 2008, Exchange 2007, IIS.
I they were able (until recently) to connect to OWA by https://mail.domain.com/owa.
Then it suddenly stopped working. I get an error The web page at https://mail.xxxx.org.uk/owa
might be temporarily down or it may have moved permanently to a new web address.
If I turn of SSL I can connect happily via just http. If I turn on SSL it gives me the error. I have checked IP/DNS at ISP and it's OK and resolves to the IP address. I can connect using http://IPAddress/OWA
so assume it cant be to do with the routing/DNS.
I checked IIS and HTTPS is allowed and run a port scan externally to make sure HTTPS was allowed through the firewall..all tests passed.
If I enable SSL all stops working on OWA even from within IIS where it gives you the option to browse.
I assume it cant me the certificate if I am not getting error messages on the local LAN with outlook??
Any help to shed light on this would be greatly appreciated.
