Procedure to remove old database from EV Journaling
We are in the process of migrating our Exchange infrastructure from on-premise to a cloud-based IAAS environment. We use EV purely to archive the journal mailboxes on each MDB. So what we have done so far is empty one of the MDBs and the only mailbox left on it is the journal mailbox. Is it possible to remove that mailbox? I'm primarily concerned about what the behaviour would be if that mailbox is deleted. Our compliance/security team use the journal for discovery cases quite often and I need to ensure that the archive for this MDB will always be fully available/searchable.
If it is possible to decommission/remove the journal mailbox, then would the following be a correct procedure to get rid of it?
1) Disable journaling on the MDB at the Exchange level (using EMC/shell)
2) Remove this MDB as a target inside EV console
3) Delete the mailbox
Many thanks for your help!
