Hi all,My company has recently been split in to two separate organizations. We have made a new forest for the new company and they are located on the same physical network for a transitional period of 12 months.One domain is a Windows 2003 domain running in 2003 native mode running Exchange 2003. The other is a Windows 2003 domain running in 2003 native mode running Exchange 2007. There is a two way forest trust between the domains.For the transitional period I need to set up address books for the other domain in each domain, can anyone help me out or point me at an article that explains how this might be done?Cheers,Evan

Create a new OU in your Active Directory & add users from other domain as "Contacts" .
