Currently our Autodiscover is set up as per Method 1 in the MS Autodiscover Whitepaper at:
We currently have 10 domain names that Exchange is working with. Any user of the primary domain (the domain where OWA services can be found) have no problem connecting. Using any other domain causes failures to connect and or certificate errors
Can anyone give me the best way to configure autodiscover so that any user can connect regardless of the email address they are assigned. Please include exactly how to set up the DNS records for the domains as I feel this may be my problem.
