Hi All, Can you please help. Everything I have read indicates that I cannot run two instances of Exchange Server 2003 under one active directory. However I am being told by a tech guru that thisis possible. Is this possible ?. thanks

You can only have 1 exchange orginization per forest, but you can have many exchange servers/sites/domains.

Thanks for the reply. How do I get the multi domain/exchange instances. Is it possible to have more than one Exchange servers linked to a user in AD ?. Outlook only appears to be able to handle one Exchange Server ?. Thanks

There is a one to one relationship between users and mailboxes if that is what you are looking for. however, 1 user can have many email addresses.
