This guide details the steps involved in configuring SMTP Journaling for Exchange 2016 or 2013, to work with the Mimecast platform. The process works for both standard and premium journaling, as the process is very similar. The only difference is the steps to enable journaling in your Exchange environment.


Mimecast Configuration


The following configuration is required inside the Mimecast Administration Console:

Exchange 2016 or 2013 Configuration


Configuring an External Contact


The next step is to create an External SMTP Contact in Exchange 2016 or 2013, using the following format: 
(where is the primary SMTP domain).

To configure an External Contact:

  1. Log on to the Exchange Admin Console (EAC).
  2. Navigate to the Recipients menu item on the left of the page.
  3. Select the Contacts link.
  4. Click on the + icon followed by Mail Contact. The New Mail Contact popup window is displayed.
  5. Complete the New Mail Contact fields as follows:

    Field / OptionValue
    First nameEnter a first name for the journaling contact (e.g. SMTP).
    InitialsThis field is not required and can be left blank.
    Last nameEnter a last name for the journaling contact (e.g. Journaling).
    *Display nameThese fields display a continuation of the First Name and Last Name fields and can be left with the default values. If the above examples are used, the display name is "SMTP Journaling".
    *AliasEnter an alias for the contact (e.g. Journaling).
    External email addressEnter the journaling address created in the Administration Console (e.g. "").
    Organizational unitBy default the path to the Users container is displayed under Organizational Unit (OU). To modify this field, click Browse, and then select the required OU.
  6. Click on the Save button. The External Contact is now configured.


Configuring the Send Connector

If your Mimecast subscription includes the Journaling feature, and your service was provisioned after the 26th March, 2015, you will find a Journal Connector has already been created for you, including an internal journal domain and journal address. The Journal Domain is automatically created as, where is the domain your organization provided as your primary mail domain. The Journal Contact is automatically created as Use this address as the mail attribute for the external contact you create in Exchange to send journal messages to.

If your Mimecast service was provisioned before this date, or you want to add an additional journal connector, you will need to manually add a journal domain, journal address, and journal connector as detailed below.

This step enables archiving of internal and external emails to the External SMTP Contact created above.


To configure the Send Connector:

  1. Log on to the Exchange 2016 or 2013 Administration Center.
  2. Navigate to the Mail Flow | Send Connectors menu item.
  3. Click the + icon. The New Send Connector page is displayed.
  4. In the Name field, enter a name for the Send Connector.
    For example: "Journal Send Connector to Mimecast".
  5. For Type, select Custom. When completed click Next:
  6. Under Network Settings select Route mail through smart hosts. When completed, click the + icon to add a smart host.
  7. Depending on your geographical location, use the table below to enter the Primary and Secondary smart hosts.
  8. Click Save when completed.

    Europe (Excluding Germany)



    South Africa


    Off Shore

  9. When both Primary and Secondary smart hosts have been entered, they should look similar to below. Click the Next button.
    Send Connector
  10. Under Smart Host Authentication, select the None button, then click Next.
  11. Specify the Address space for which the connector should route mail, by clicking the + icon and adding a domain.
  12. In the Add domain dialog box that appears, enter the following information:
    1. *Type: SMTP
    2. *Full Qualified Domain Name (FQDN):
      (The same journal sub domain configured per the "Mimecast Configuration" section of this document).
    3. *Cost: 1
  13. When completed click Save. The added domain will be listed.
  14. Click on the Next button.
  15. Click on the + icon.
  16. Select the transport server(s) that will associate with this connector.
  17. Click on the Add button to add the server(s).
  18. When the server(s) are selected click OK.
    If running an environment with Edge Transport Servers, you'll need to push the Send Connector to Edge Transport Servers. Visit the Microsoft website for further instructions.
  19. Click on the Finish button. This concludes the steps in configuring a Send Connector.
    Check the Send Connector's properties to ensure there are no size limits set, as shown in the image below. By default, a 10mb size limit is set on the connector. This can cause larger messages to build up in your queues.

Enabling Exchange Journaling


The next step is to enable journaling from your Exchange 2016 or 2013 environment. Follow instructions in the subsections below for either Standard or Premium journaling.

Standard journaling is allowed using the default Client Access Licenses from Microsoft. Premium journaling requires Enterprise CALs from Microsoft.

Standard Journaling


To enable Standard journaling:

  1. Log on to the Exchange 2016 or 2013 Administration Center.
  2. Navigate to the Servers section.
  3. Click on the Databases tab. 
  4. Select a listed database.
  5. Click on the Edit icon to go into the database properties.
  6. In the database properties, select the Maintenance tab.
  7. Click on the Browse button next to the Journal recipient field.
  8. Select the Mail Contact created earlier, then click OK.
  9. Click on the Save button to enable Journaling for that database.
  10. Repeat the process for the other mailbox databases. This concludes configuration for Standard journaling.
    Public Folder Databases cannot be journal enabled.

Premium Journaling


To enable Premium journaling:

  1. Log on to the Exchange 2016 or 2013 Administration Center.
  2. Navigate to Compliance Management.
  3. Go to the Journal Rules tab.

    4. Journal the following messages: Select the All messages option.

  6. Click on the Save button to finish. This concludes configuration for Premium journaling.

Verifying Standard or Premium Journaling


After Journaling is configured, the next step is to verify that the connections are working.


To verify Exchange 2016 or 2013 Journaling:

  1. Log on to the Mimecast Administration Console.
  2. Navigate to Administration | Services | Journaling.
  3. Note the Service Status of the Journaling Connector:


    IconService StatusDescription
    Pending.gifService Awaiting Initial RunOn initial configuration, the status icons for SMTP journal connectors will be orange, with a service status of Service Awaiting Initial Run
    Successful.gifService OKOnce the first message is received by the connector, the icon will change, and the status updated to Service Enabled
    Failed.gifService ErrorIf Mimecast cannot connect to the Journal Connector and retrieve emails, the status will change to Service Error
    If the connector configuration is not successful, please see the Troubleshooting Journaling article.
  4. View the current list of Journaling items by clicking the Queue Details button.

    For Exchange Envelope Journal Format (EJF), the actual recipient is displayed as the sender and the journal address as the recipient.

Now that Standard or Premium Journaling is configured and working for Exchange 2016 or 2013, you can move to step 5 in the Connect process.
