Due to issues with a raid controller i have been forced to build up a new exchange 2010 (dont ask....) server and migrate data from the current server to the new one.
I have got all mailboxes moved across and so as far as i can tell setup everything else that is required.
I thought i was at the stage of just repointing the firewall to the new server but when i quickly tested this clients couldnt reconnect. the server is responding to 443 and 25.
Is there a final switch over process i need to do within exchange?
