EXCH01 - All Roles
EXCH02 - All Roles
Three databases setup in DAG.
The problem is when the engineer setup these Exchange servers, he left the FQDN as the Internal Host and OutlookAnywhere address on each server. So if a server goes down, Outlook stops working for many people. I am looking to update all the Virtual Directories and OutlookAnywhere to use mail.domain.com. Normally I would have set this up from the beginning and wouldn't have to worry about it. I don't like making changes without knowing the impact. Right now if you look at the Exchange Proxy Settings in Outlook, everyone is either pointing to exch01.ad.domain.com or exch02.ad.domain.com.
For one, do I need to update the Virtual Directories to use mail.domain.com or can I just update OutlookAnywhere? Once I make these changes on the Exchange server, will it have any impact on the end users, or will Outlook automatically update with mail.domain.com the next time they connect? The SSL certificate already has mail.domain.com listed, but it is currently only being used for OWA via a firewall NAT policy. No External URLs have been setup as I believe they only want people using Outlook internally or through VPN.
