Our company is called domainA.com. They have opened a brand new company called domainB.com. What is the best way to create a domain for domainB so both domains can use the same exchange 2010 server to send and receive email? I want users in domainA to keep their user@domainA.com email address while domainB users have user@domainB.com, and not, user@domainB.domainA.com.
Thank you!
