Hello,
I am doing a POC implementation for a customer (who are on say Domain A) who has a hosted exchange server in their parent company (say Domain B)
Linked mailboxes are created for users in Domain A on Exchange server in Domain B
The POC is on a purely test environment. Please find the brief overview of the environment:
Domain A:
Machine 1: Primary Domain Controller
Machine 2: Exchange 2010 HUB/CAS
Machine 3: Exchange 2010 MB
Domain B:
Machine 1: Primary Domain Controller
Machine 2: EV/SQL Server
I have created a two-way transitive trust between both domains. I am able to create linked mailboxes for domain A on domain B.
Vault service account is created on Domain A. This is the local administrator on EV server and permissions and throttling policy is applied through PS scripts provided with the installation.
I am able to create an outlook profile on EV server for DomainA\vaultadmin and it is able to reach the Exchange server.
There are no Exchange related errors on the Deployment Scanner.
Problem Faced:
I am able to add Domain B on my EV server without any issues. But when I try to add the MB server in the Domain B. I get an error "Unable to connect to Exchange server . Kindly check that the Computer is in the Network."
I am able to ping all the Domain B servers from my EV server. I even tried manually adding the GC server for Domain B in EV Target Domain properties.
But still EV is somehow not able to reach the Exchange server.
Is there anything I might have missed during the configuration that might be causing this?
Are there any additional permissions required on Exchange server for VSA in a cross-domain environment?
