How do I archive emails from Microsoft 365/Outlook?
Last updated: April 14, 2026
Setting up Journal Rule
Visit the Microsoft Purview compliance portal. Search for the word "journal" in the search bar, and click on the option that says Data Lifecycle Management > Exchange (legacy).
Conditional
If you see a red banner, click Settings and enter an internal email address to receive Non-Delivery Reports (NDR).
Select + New Rule and enter the following information:
Find your unique journaling address in the Hadrius platform at Email review > Manage > Journal addresses, or this can be provided to you by the Hadrius team. Please note that this address is case-sensitive.
Note: Use the complete email address (e.g., yourcompany-abc123@journaltohadrius.com) wherever you see <archive_subdomain>-<secure_key>@journaltohadrius.com in the instructions below.
Send journal reports to: |
|
Journal rule name: | Hadrius Archiving |
Journal messages sent or received from: | Everyone |
Type of message to journal: | All messages |
Select Next, review the settings, and then Submit to create the journal rule.
Sometimes the journal rule name gets overwritten when you choose which type of messages to journal, so keep an eye out!
Mail Flow Connector
Conditional
If you use an outbound email relay service (such as ProofPoint, Mimecast, Barracuda, etc.), you might have to add a new connector on your Exchange admin center, as the journal rule by itself might not be sufficient.
In the Microsoft Exchange admin center, navigate to Mail Flow > Connectors. Select + Add a connector and enter the following information:
Connection from: | Office 365 |
Connection to: | Partner Organization |
Connector name: | Hadrius Archiving |
Use of connector: | Only when email messages are sent to these domains |
Domain: |
|
Routing: | Use the MX record associated with the partner’s domain |
Security Restrictions: | leave defaults as‑is |
Validation email: |
|
Important: In the connector setup, the Domain field requires only journaltohadrius.com (the domain portion), while the Validation email field requires your complete journaling address (e.g., yourcompany-abc123@journaltohadrius.com).
