  • Is possible to have 2 Seprate Exchange 2007 Enviroments within same Domain?

    We are trying to evaluate the possibility of managing our own Exchange 2007 Servers hosting our companies mailboxes. We currently share a Domain with our Parent Company who also manages the existing Exchange 2007 environment.

    Would it be possible to move our mailboxes onto our own EX2007 Mailbox, Hub Transport and CAS servers??? The goal here is to have the Exchange Servers that are related to our company entirely in our own hands. I know you can only have 1 Exchange Organization per forest, but don't know the extent of what can be done within the same domain. So with that said, can we have Exchange Servers A and Exchange Servers B with each companies mail respectively on their mail servers without sharing the other roles, CAS and Hub Transport within the same domain?

    Other options would be to separate into another Domain within the Forrest, but we still share many other applications and having mail in our hands is enough right now.

    I have little experience with Exchange 2007 and am reaching out for help. This is a current issue we have to solve so thanks in advance!

    No.
    Exchange org boundaries are the forest. Therefore if you want a separate system you will need a separate forest, with separate machines, user accounts etc.

      Simon,

      Thanks for your response. Let me rephrase the question. Can we limit our users to specific mailbox servers and hub transports within the same exchange organization????

      We all still share the same domain, but need to make sure our users mail is in our hands.

      A separate forest was in the works until we found out our phone system will not work.

      Thanks!

        Yes, it's possible, you have to create your own AD site through designing and managing IP subnets. Then you can place your company Exchange server within this site.

        But you should be aware that this is still the same AD forest/domain, so someone with Enterprise Admin, Domain Admin or Administrator (at domain level) privileges might be able to get control and/or access to your server.

        It might be good to know what your goals are with separating your Exchange server.

          It is possible to have some degree of separation, but you would not be able to keep the admins of the other site out of your servers. The root of the domain/forest is in control and then control is delegated down. You wouldn't have control over the Exchange org settings for example, or if you did, those would be the same settings as used for everyone else.
