That is incorrect, for the most part. You can have as many separate email domains (ie @company.com) on an Exchange server as you want, but there can be only one Exchange organization per forest. Therefore, there is no difference between parent/child domains and two tree domains - both would have to be served by a single Exchange organization.
Microsoft maintains a good set of resources in their Service Providers section that has links to whitepapers on hosting multiple companies on a single Exchange organization. http://www.microsoft.com/serviceproviders/ Roger -------------------------------------------------------------- Roger D.
