  • can you raise a forest AD level to something higher than its root?

    due to interoffice politics, our office does not have admin access to the root domain or its DCs or GCSs.

    We want to install an Exch 2010 server to coexist with our Exch 2003 server, but we will have to raise our AD level from 2000 native to 2003 native.

    Is this possible to do without compatibility issues with our root domain, or other forests in our org?

    The following link details the supportability matrix for Exchange Server:

      To summarise, Exchange 2010 requires 2003 Domain and Forest FLs, and Server 2003 DCs in the Exchange domain.

      By the looks of it you will need to negotiate with the owners of the root domain and persuade/blackmail/threaten them until they raise the forest (and obviously all domains in it)

      The alternative is a separate resource forest, with a domain trust to your domain
