The process of configuring SMTP journaling uses both the Commvault software and the Exchange server.
How you perform each procedure depends on whether your Exchange server environment is on-premises or hosted (Office 365 with Exchange).
The following is a high-level description of the configurations that you must perform on the Exchange server.
Steps to Configure the Exchange Server for SMTP Journaling
- 
Create a remote domain. A remote domain so that the journaled messages can be sent outside of your organization to the ContentStore Mailbox. 
- 
Create a mail contact. The mail contact is the external email address of the ContentStore Mailbox that will receive the journal reports. 
- 
Create a Send connector. The Send connector sends the journal reports to the ContentStore Mail Server (SMTP). 
- 
Create journal rules. 
How you perform procedure for each step of the process depends on whether you use on-premises servers or Office 365 with Exchange servers.
