Hi - I have an Exchange 2010 Standard server and standard CALs. I want to be able to make it so we can have a central contact database or a way to push contacts out that a delegated adminitrator specifies to all users so we can keep a common list of contacts for our techs in the field (other employees, vendors, etc). We have Androids, iPhones, and WM6.5 phones but mostly have Android's using the NitroDesk TouchDown client. I am open to purchasing Exchange Enterprise CALs if that is necessary. How can we do this?
