The connector is created.

Step 2. Create a Non-Delivery Report Recipient

Before creating journal rules, specify a journal recipient for non-delivery reports (NDRs) to reduce the risk of losing journal reports:


To create an NDR recipient:

  1. Log into your Office 365 Exchange admin center.
  2. Select compliance management > journal rules.
  3. If an NDR email recipient is not already specified, click Select address to the right of Send undeliverable journal reports to field:
  4. Browse to and select a recipient from the address book.

  5. You can search for a recipient by typing all or part of a display name, and then clicking the Search icon, or click on either the Display Name or E-Mail Address heading to sort the list.

  6. Click OK once you select a recipient, and in the NDRs for undeliverable journal reports window, click Save.

    Best Practice

    Create a shared mailbox and use that mailbox as the NDR recipient.

Step 3. Configure Office 365 to Send Journal Mail

  1. Log into Office 365 Exchange admin center.
  2. Select compliance management > journal rules.
  3. Click the + symbol. In the new journal rule dialog box, complete the following:
    1. Send journal reports to – Enter the journaling address from the Mail Sources > SMTP Journaling page in the Barracuda Cloud Archiving web interface. This is called the journaling mailbox.
    2. Name – By default, the name of the journal rule is automatically generated from the journal recipients. If there are existing journal rules that contain the same journal recipients, numbers are automatically appended to the journal rule name to avoid duplicates. If you choose to override the automatically-generated name by typing in a custom name, verify the name is unique and descriptive.
    3. If the message is sent to or received from – Select Apply to all messages to journal all recipients.
    4. Journal the following messages – Select All messages to journal all messages regardless of source or destination:

      Because the journaling mailbox may contain sensitive information, it is recommended that you create organization-wide policies that govern who can access the journaling mailboxes in your organization.

  4. Click Save. The rule is added to the journal rules table.

Once you complete your deployment configuration, mail begins forwarding to the Barracuda Cloud Archiving Service. Log into the web interface as the administrator, and go to the Basic > Dashboard page. Processed mail displays in the Message Statistics table. Statistics are cached and may take up to 30 minutes to appear.

For additional configuration options and features, log into the web interface and click Help.
