So we have deployed a new 2010 environment within our 2007 environment.
We have our cas array, (which is being load balanced through an F5)
the fqdn is servername.corp.domain.org
when our outlook client connects it fails when connecting saying exchange isnt available.
through some tracing on the F5 it shows the generated request in outlook is going to mail.domain.com
we do have an A record entry for mail in our domain.com dns
we do have an A record entry for our cas array in both corp.domain.org and domain.com dns
we do utilize a split dns.
if I manually point a mailbox DB to a single CAS this works, if I edit my host file to use a cas with the casarray.corp.domain.org this works also. unsure if this is an F5 problem
I'm wondering if this is a problem with IIS headers.
any ideas where to start?
I can log into mail.domain.com/owa without issue
