I have 2 AD Sites, EAST and WEST. Each Site has their own CAS array and DAG, MailEast and MailWest for the casarrays, and DagEast and DagWest for the Dags.
Each CAS Array in both sites are pointed to the same external URL mail.company.com/owa for OWA. The internal URL's for each CAS server, http://
<cas server name>/owa. We are utilizing a HLB that uses VIP to point users on the east site to the EAST CAS and users from the west site to point to the west CAS.
If a users mailbox is located in the MBX Eastdag, and I try navigating to the external url, https://mail.mycompany.com/owa
from the west site, I get a message stating: "A server configuration change is temporarily preventing access to your account. Please close all Web browser windows and try again in a few minutes. If the problem continues, contact your helpdesk."
If I try navigating to https://maileast/owa
from the west site, or I am located in the east site and use https://mail.mycompany.com/owa
, I get to my mailbox just fine.
What am I missing here, why can I not use the WEST CASARRAY and be pointed to my MBX located on the EAST DAG? I would like to successfully be able to use the external URL from both sites, and not use the CASArray names to access mailboxes.
This is a new setup. We are making it so that both Sites CAS Servers are pointed to the internet as well.
