The Exchange Mailbox Journal Mailbox works in conjunction with the message journaling feature of Microsoft Exchange Server software to archive all incoming and outgoing messages and attachments. A copy of all incoming messages and outgoing messages are captured in the Exchange Journal Mailbox, which is then archived with the Exchange Mailbox according the to the schedules that you create. Incoming messages are written to the journal mailbox as they come into the Exchange server. Therefore, all messages are recorded, regardless of whether the message recipients delete the message in their mailboxes.
The archived data remains available for retrieval for the length of time set in the Commvault Exchange journal plan. During this period, the data is readily available for access and retrieval by authorized users. All archived data is protected from any edit or alteration from all users within the context of the archival system (that is, the archived data on the storage media cannot be written to or altered).
Before you set up Exchange Mailbox in the Command Center, perform the prerequisite tasks. After you set up Exchange Mailbox in the Command Center, perform the configuration tasks.

Exchange Online
For journaling Exchange Online mailboxes, you can use the SMTP journal Solution ContentStore Mailbox. It eliminates the need for an on-premises Exchange Server and ensures better performance than the journal mailbox solution.
You cannot designate an Exchange Online mailbox as a journaling mailbox. You must create an Exchange Online journal rule to deliver journal reports to an on-premises journal mailbox.
Exchange Hybrid
For an Exchange hybrid deployment with the mailboxes split between on-premises servers and <Exchange Online>, you can designate an on-premises mailbox as the journaling mailbox.
