Can anyone recommend a solution for the following scenario?
Exchange server is used by 6 different small companies. Each company requires its own offline address book and its own backup.
What is the scalability of this model, i.e how many companies\clients can operate efficiently on one installation of Exchange at optimal performance. What version of Exchange (i know its not possible on 2003)? Any other suggestions?
The exchange installation is eventually going to be virtualized.
Thanks you in advance.
