Here is my setup:
Two locations – Main and DR Site
Two Exchange 2010 servers - HT, MB, CAS roles
CAS Servers - CAS1 (192.168.0.8) and CAS2 (192.168.0.9)
CAS Array – outlook.domain.com (192.168.0.11)
DR Site (Azure)
One Exchange 2010 Server – HT, MB, CAS roles
CAS Server – CASDR (10.10.10.8)
CAS Array – outlookdr.domain.com (10.10.10.11)
DNS entry for outlookdr.domain.com
First, everything works fine in the main site and we are adding Azure as the DR site.
I am able to ping CASDR from either Azure or the main site.
I am able to connect to CASDR from our test account (in Outlook and OWA) to our test database that is in Azure.
I am not able to ping outlookdr (10.10.10.11) from the main site or DR site. Ping returns the correct IP address of outlookdr (10.10.10.11).
When I place CASDR into outlookdr, I am not able to access my test account via Outlook or OWA.
Why is this happening?
