Hey guys, so heres my scenario, we were testing a primary site dag outage, and not for all the tea in China would outlook connect to the DR sites CAS server. When I look at outlook its still trying to connect to thecas server in my primary site, when I run theautodiscover test from the clients outlook, within the output, I see it fails on the primary and goes to DR CAS as it should, I even did a repair and that didn't work.
i had to edit the host files on the client and point it directly to the DR server and then it connected, and by that i mean, it kept trying to connect to EX01 instead of DR01, soi edited the host file to make the client go to DR01 as EX01, which worked, so I'm not sure what's going on. All of this is internally btw.
Current design:
Exchange 2010 SP2 - 1DAG (3 members)
"Primary site": 2 DC's, 2 DAG members, 2 Hub/CAS
"DRSite"; 1DC (Alternatewitness), 1 DAG member running all roles
Testing server blackout scenario at the primary site, was able to get mailboxes mounted on DR site, OWA works, able to receive mail, outlook only works if DNS is reworked.
Thanks in advance for any suggestions.
