I'm looking for advice from someone that currently uses envelope journaling. We use one Exchange Server 2003. We have 8 stores roughly hosting 125 Mailboxes per store. We want to implement envelope journaling but I have a few questions about the possible hardware costs we need to budget for:
1. Will we need a separate server to host the journal mailbox or can we have the journal mailbox on its own Storage group/Store on our current exchange server? If a separate server is needed, can it be a VM?
2. How long do you keep the journal emails in that mailbox before you archive them using a third party software?
3. Do you have a separate server for the third party archiving software? We'll be using CommVault Exchange Compliance Archiver.
