Autodiscover, following a migration from Exchange 2003, issues CASServer1 for some users and other users CASArray. I'd like to set Autodiscover to hand out CASArray for each user. The OAB, RPC, OWA, EWS all are set with the mail.domain.com are working as they should. However, when Autodiscover is handing out Server1 to Outlook clients when they logon, I lose the redundancy which I hoped to get by deploying two cas servers. Does anyone know how to set the Autodiscover to hand out CASArray as opposed to Server1 to Outlook clients?
