We are currently hosting 15 corporate domains under our domain and we don't want to install HMC in order to use 2007. We have removed the Global Address List. When we try to install the new Exchange 2007 we get the following message:

Error

Active Directory operation on dhi02.dhinnovations.com. The object 'CN=All Contacts, CN=All Address List, CN=Address List Container, CN=DH Innovations LLC, CN=Microsoft Exchange, CN=Services, CN=Configuration, DC=dhinnovaitons, DC=com' already exits.

The object exist.

How do we get around this message

We had looked at that the problem is that we have 15 seperate companies that we are providing Exchange hosting for. We use security permissions to hid each companies address book from the other. I have been told that in Exchange 2007 we would no longer be able to do this. Can you confirm that this is true, if so I will follow through we this work around.

Thanks - Chris
