I'm trying to setup an Exchange 2013 environment with 2 VM servers in Hyper-V. 1 virtual server will be a mailbox role and 1 will be CAS.
Inside Hyper-v I have 2 virtual networks configured - 1 with internet access and one without. I was hoping to have the mailbox server not connected to the internet, and the CAS server would have 2 network connections.
Everything works fine for receiving emails, however I cannot send external emails as the DNS lookup fails. As soon as I connect the 2nd network connection to the Mailbox Server all emails in the queue are sent.
Is it possible to setup a mailbox server without internet access and have a send connector forward all emails to CAS to resolve dns, or do I need at least 1 mailbox server with internet access to have the send connector?
Update: This is the error I get in the Queue Viewer (sensitive data replaced with "MailboxServerName" or "Domain"):
