We're running in coexistence mode with 2013 and 2007. We had one of our 2007 CAS servers go down. We have IMAP users that keep getting a login prompt now. Looking at the IMAP logs it's failing when the 2013 CAS server tries
to proxy the IMAP session to the down 2007 CAS server. Is there any way to stop 2013 from attempting to proxy to the down 2007 CAS server? We have 3 other 2007 CAS servers that are available.
