Hide child domain GAL from exchange users in parent domain

I was wondering if someone would be able to tell me how to hide the child domain GAL from exchange users in the parent domain.  For example, parent domain is called domain1.local and child domain is called child.domain1.local.  Now, if the child domain exchange users use a @domain1.local suffix is it possible to hide the GAL from the parent domain?  if not is it possible to change the suffix to @child.domain1.local? so the email address would be test@child.domain1.local.

any advice or ideas on how to do this would be very welcome.

i don't think it is possible to hide it from parent domain, as you can have one exchange org per forest. One option is to create different forest for child domain.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Add a new Recipient policy for child domain and move it above default policy

Adding new email address policy for child domain, could be the solution, but i don't think you can hide.

Would you know if it is possible that once the new child domain address list is created, will users in the parent domain see this new child domain list? is there a way to hide this list, or create a policy to deny users in the parent domain acces to view this list?

hmmm, I know this is off topic for this question, but would you by chance know of a link so I can read more on creating a different forest for a child domain?

Problem is that the child domain needs to us CA from the parent domain and needs to access several databases.
