25.21.1.Configuring Microsoft 365 journal forwarding through third-party Exchange Online Protection
This section applies to the contentACCESS SMTP configuration.
The default Exchange Online Protection for Microsoft 365 allows journaling without restrictions. However, if your Microsoft 365 organization is using a third-party Exchange Online Protection, journal forwarding requires additional configuration.
Exchange Online Protection does not allow forwarding emails to an external organization unless that organization is explicitly permitted. Since the contentACCESS SMTP server is not permitted in your Microsoft 365 environment, a new connector will need to be created. This connector will enable access to the contentACCESS SMTP server from your Microsoft 365.
Summary of steps in this guide:
- add a new mail flow connector
- configure email routing
- validate the connector
The following steps will guide you on how to set up a new connector:
1. Navigate to the Exchange admin center -> Mail flow (on the left panel) -> select the Connectors option.
2. Open the New Connector tab by clicking the Add a Connector button, and select the Office 365 option in the Connection from section first, then select Your organization’s email server in the Connect to section. Then click Next.
3. On the Connector Name page, name the new connector, add a description (optional), and check the Turn it on checkbox before clicking the Next button.
4. The next step is to add the domain to the section Only when email messages are sent to these domains on the Use of connector tab.
5. After this, add the name of the server to which the emails are sent – this is the contentACCESS server.
6. On the Security Restrictions tab, you need to turn off Transport Layer Security (TLS) for this connection. Then click Next.
7. As the last step, you need to specify the email address used to receive the journal emails.
8. On the Review Connector page, check the configuration of the connector, then press the Create Connector button.
The newly created connector will appear on the Connectors page.
