I am using native Exchange 2013 Journaling for journal all external messages for all users. The size of journal mailbox is very huge. I am looking for best practices for journaling in terms of journal mailbox size? Journal database size? Do I need to create multiple journal mailboxes? Do I enable achieving for journal mailbox? If archiving enabled, then what is max size for archive mailbox? I do not want to export mails to PSTs.
Appreciate help from others
