I have setup two exchange 2010 Mailbox & CAS servers in a DAG. My B server works fine if you take the a server offline. But if I take the B server offline my outlook clients can not connect to the server.
"there is a problem with the proxy servers security certificate. The security certificate is not from a trusted certifying authority.
Outlook is unable to connect to the proxy server server.domain.com. (Error code 8)
any help is appreciated.
