Exchange 2010 OWA CAS Proxy
Hi all and thanks for any assistance you might be able to give me.
I have exchange 2010 - 2 CAS mailbox servers in 2 locations - same domain - DC's in both locations. We had an outage and my webmail seems to be hosed. Site A is internet facing Site B is not. All webmail access goes through site A - my setup before would proxy back to the first server and load the mailbox. It now appears to have lost permissions. here is the error I get when i try to login externally... im sure youll need more info just ask away :) and thanks again
