We are using one forest-multi domains model as describe below
company1.local is the root domain in forest ( I'm using regional domain as root ). External domain : company1.com
company2.local is the other domain which has external domain named company2.com
Is it possible for deploy only 1 All-in-one Exchange 2010 box in company1.local domain but serves both domain AD users with their owned external domain name ? is it right that Exchange 2010 Multi-tenancy will do the job ?
And what happend if the AD model become Parent-Child model in which there is a blank root domain with Exchange box deployed and company1 and company2 become child domain. I've read somewhere in the Net that Exchange box that deployed in root domain can serves the child domain users ( with preparealldomains switch ), but how about the different of external domain name ?
Any help would be appreciate !
