I have 2 Exchange 2010 Servers running at different sites in an Exchange cluster. Both Exchange servers reside on a VM cluster as well.
All sites are in my MPLS
I am having issues where the server at the primary site goes off line for a short duration,(exchange migrates to another physical host) and so the other server at the other site takes control. (I know this is normal ). The issue is I only have 1 firewall, (one inbound/outbound address for SMTP) and when Exchange fails over to the secondary server I can no longer get external email and all of my PDA devices lose connection to there mailboxes.. I then have to manually go back and move the databases back under the primary server in order for mail be delivered externally.
Is there some way I can turn this off? I want the cluster to exist in case there is a true disaster and I need to reroute mail..
I would like to manually decide when to switch over to the secondary Exchange server as I deem necessary..
