Hi guys, really hoping that someone can help me with configuring SMTP Namespace Sharing between two Exchange Forests on the same LAN.
Basically, I have created a new forest and installed a new exchange organisation in this forest. Both forests are located on the same IP subnet and a two way trust has been created between the forests. Federated sharing has also been configured. I can use ADMT to migrate the user and computer accounts to the new forest and also migrate test mailboxes over. Ideally, I want to be able to do the mailbox migrations in stages so will need to be able to have mail flowing between the two forests. I have read over the following article (http://ibrahimnore.wordpress.com/2012/09/06/configuring-smtp-namespace-sharing-between-two-exchange-forests-part-2/) which is good but it's demonstrating over the internet, can anybody advise how this can be achieved on the local LAN?
Any help greatly appreciated :-)
