Our Exchange server currently hosts email for two other companies and we are about to beging hosting email for another sister company. I am wondering how to best accomplish this with regards to EV and maintaining separation.
We currently have a different Exchange 2007 storage group for each of the companies, but each storage group is also currently pointing to the same journal mailbox that exists in the main storage group. My first thought was to create a new journal mailbox in the storage group for the company we are about to host email for and have their journal messages be sent to that separate mailbox.
I'm not sure if this is the best thing to do. Do I then add this new journal mailbox as a target in EV for that Exchange server? Is this even the best way of accomplishing the task?
The goal is really to keep their email separate in the sense that we will be providing them with access to Compliance & Discovery Accelerator. We don't want them to have any access to messages that part of our other companies. There are other questions I have that I can't quite formulate into words until I understand the best path to take.
Any input would be greatly appreciated!
