Hi, I have 2 company xyz.com and abc.com.now both companies using Exchange Server 5.5. Now both companies are going to merge and wants to come under same Email domain name RPX.com.Both companies want to put email address same as @RPX.com.when these both companies change Email addresses as @RPX.com.and set as Reply address is @RPX.com. Any user from previously named domain xyz.com(current is RPX.com) sends email to abc.com(current is RPX.com).the user get delivery failure notice because it shows that the user is not in GAL.Can it be possible that user from xyz.com(current is @RPX.com) send email to abc.com(current is @RPX.com) by someway. There is one solution to create custom recipient for both organisation.for xyz.com create custom recipient of abc.com and vice versa. Is there any other solution so user from abc.com(currently @RPX.com) sends email to xyz.com(currently @RPX.com) goes as external mail ?Waiting for a kind responseThanks in AdvanceZaf
