Office 365 journaling setup

Area 1 has been renamed

Area 1 is now Email Security (formerly Area 1).

For customers using Microsoft Office 365, setting up Email Security via journaling is quick and easy. The following email flow shows how this works:

Note

Email Security (formerly Area 1) supports Microsoft Office 365 Government Community Cloud (GCC). Refer to Microsoft 365 Government Community Cloud for more information.

Journaling

1. Configure connector for delivery to Email Security (formerly Area 1) (if required)

Note

Email Security only scans inbound emails.

If your email architecture does not include an outbound gateway, you can skip this step and proceed to the next one.

On the other hand, if your email architecture requires outbound messages to traverse your email gateway, you may want to consider configuring a connector to send the journal messages directly to Email Security.

1. Log in to the Exchange admin center ↗, and go to Mail flow > Connectors.

   

2. Select Add a connector.

3. Configure the new connector as follows:

   • Connection From: Office 365
   • Connection to: Partner Organization

   

4. Select Next.

5. Configure the connector as follows:

   • Name: Deliver journal directly to Area 1
   • Description: Deliver journal directly to Area 1
   • Turn it on: Enabled.

   

6. Select Next.

7. Configure the Use of connector setting as follows:

   • Select Only when email messages are sent to these domains.
   • In the text field, enter journaling.mxrecord.io as the host address, and select + to add the domain.

   

8. Select Next.

9. Configure the Routing setting as follows:

   • Select Route email through these smart hosts.
   • In the text field, enter journaling.mxrecord.io as the smart host ↗ address, and select + to add the domain.

   

10. Select Next.

11. In Security restrictions, you need to keep the default TLS configuration. Review the following settings:

    • Make sure the Always use Transport Layer Security (TLS) to secure the connection (recommended) checkbox is selected.
    • In Connect only if the recipients email server certificate matches this criteria select Issued by a trusted certificate authority (CA).

    

12. Select Next.

13. You need to validate the connector by using your tenant’s specific journaling address. To find this address, go to the Email Security dashboard ↗ > Support > Service Addresses page.

    

14. Add the address and select Validate.

15. Once the validation completes, you should receive a Succeed status for all the tasks. Select Next.

    

16. Review the configuration and select Create connector.

    

Your connector is now active. You can find it in Exchange admin center > Mail flow > Connectors.

2. Configure journal rule

1. Log in to the Microsoft Purview compliance portal ↗.

2. Go to Data lifecycle management > Exchange (legacy).

3. Select Settings (the gear icon).

4. In Send undeliverable journal reports to enter the email address of a valid user account. Note that you cannot use a team or group address.

   

5. Select Save.

6. Still in the Exchange (legacy) screen, select Journal Rules.

   

7. Select New rule to configure a journaling rule, and configure it as follows:

   • Send journal reports to: This address is specific to each customer tenant, and can be found in your Email Security dashboard ↗. For example, <customer_name>@journaling.mxrecord.io.
   • Journal Rule Name: Journal Messages to CloudflareArea 1
   • Journal messages sent or received from: Everyone
   • Type of message to journal: External messages only

8. Select Next.

9. Verify the information is correct, and select Submit > Done.

   

Once saved, the rule is automatically active. However, it may take a few minutes for the configuration to propagate and start pushing messages to Cloudflare Email Security. After it propagates, you can access the Cloudflare Email Security dashboard to check the number of messages processed. This number will grow as journaled messages are sent to Cloudflare Email Security from your Exchange server.

3. Compliance

Create Office 365 distribution lists

For compliance purposes, you might be required to process emails in certain geographic regions such as India or the EU. If that is your case, you should create Office 365 distribution lists ↗ for each geographic region where you need to process your emails, before configuring your journal rule.

Configure journal rule

After creating the distribution lists based on regions for your users, configure your journal rule:

1. Log in to the Microsoft Purview compliance portal ↗.

2. Go to Data lifecycle management > Exchange (legacy).

3. Select Settings (the gear icon).

4. In Send undeliverable journal reports to enter the email address of a valid user account. Note that you cannot use a team or group address.

   

5. Select Save.

6. Still in the Exchange (legacy) screen, select Journal Rules.

   

7. Select New rule to configure a journaling rule, and configure it as follows:

   • Send journal reports to: This address is specific to each customer tenant, and can be found in your Email Security dashboard ↗. If you need to process emails in certain geographic regions, refer to the Geographic locations table for more information on what address you should use.
   • Journal Rule Name: Journal Messages to CloudflareArea 1
   • Journal messages sent or received from: A specific user or group and select the user group you created above.
   • Type of message to journal: External messages only

8. Select Next.

9. Verify the information is correct, and select Submit > Done.

   

Once saved, the rule is automatically active. However, it may take a few minutes for the configuration to propagate and start pushing messages to Cloudflare Email Security. After it propagates, you can access the Cloudflare Email Security dashboard to check the number of messages processed. This number will grow as journaled messages are sent to Cloudflare Email Security from your Exchange server.
