# Configurations for the Exchange Mailbox ContentStore Mailbox

The process of configuring SMTP journaling is done using both the Commvault software and the Exchange server.

## Steps in the Commvault Software

1. Install and configure the Exchange Mailbox.

2. Configure the ContentStore Mail Server (SMTP).

3. Create the Exchange journal plan.

4. Create an Exchange Mailbox server.

5. Add a mailbox to the subclient and perform any other required configurations on the subclient.

## Steps on the Exchange Server

1. Create a remote domain.

   - On-premises

   - Microsoft 365 with Exchange

2. Create a mail contact.

   - On-premises

   - Microsoft 365 with Exchange

3. Create a Send connector.

   - On-premises

   - Microsoft 365 with Exchange

4. Create journal rules.

   - On-premises

   - Microsoft 365 with Exchange

## Supported Exchange Servers

- Exchange 2007 or later (on-premises)

- Microsoft 365 with Exchange

### Connecting a Remote PowerShell Session to Microsoft 365 with Exchange

For some tasks related to Microsoft 365 with Exchange, you must use Windows PowerShell to create a remote PowerShell session to Microsoft 365 with Exchange. For more information about how to create the session, see the Microsoft TechNet article "Connect to Exchange Online PowerShell", https://technet.microsoft.com/library/jj984289(v=exchg.160).aspx.

Important: Before you perform any tasks that use the remote PowerShell session, you must run the following cmdlet:

    Enable-OrganizationCustomization

You only need to run this cmdlet once. If you run it again later, you will receive an error.

For more information, see the Microsoft TechNet article "Enable-OrganizationCustomization", https://technet.microsoft.com/en-us/library/jj200665(v=exchg.160).aspx.

## Envelope Journaling

The ContentStore Mailbox can capture BCC and distribution list information if the sending mail server has envelope journaling enabled. This information is not captured if envelope journaling is not enabled. Any type of mailing servers is supported if it provides the envelope format.

Consult the documentation for your mail server to determine how to enable journaling for your mail server.

The ContentStore Mailbox will capture all other information if envelope journaling is not enabled.

## Load Balancing and Fault Tolerance

The ContentStore Mailbox supports the following methods for load balancing:

- Deploying a single send connector with multiple smart hosts

- Hardware load balancers

- Mail exchange records (MX records)

The method that you choose depends on your environment.

For more information, consult Microsoft documentation. For example, see the following Microsoft TechNet articles:

- "Load balancing", https://technet.microsoft.com/en-us/library/jj898588(v=exchg.150).aspx

- "Understanding Load Balancing in Exchange 2010", https://technet.microsoft.com/en-us/library/ff625247(EXCHG.141).aspx

## Before You Begin

Make sure that the SSL certificate is ready to be installed on the ContentStore Mail Server (SMTP). Use a digital certificate signed by the Certificate Authority (CA), and not a self-signed certificate. Make sure that SSL port 25 is open on the ContentStore Mail Server (SMTP) access nodes.
