Hello,
I would like to ask: If I have two Active Directory Sites , both with CAS, HUB and Mailbox servers ... if my Public DNS mail records (Autodiscover and mail) point to one site but this site goes down, Should I quickly change those Public DNS records so that the point to the other site?
But what would be the user experience like? They have to wait for some time to get their email ?
Do companies have Public DNS records pointing only to one site?
Thanks in advance.
Luis Olías.
