Office 365 Connectors - Summary


To use Mailprotector solutions with Office 365 (O365) domains, connectors need to be configured to establish the secure connections between the two services. Detailed configuration instructions are provided in the linked knowledge base articles below.

Applies to:

Office 365, O365, Exchange Online, Exchange Online Protection 


Before beginning the configuration of the Office 365 connectors, the Mailprotector Console should have the domain and users configured to ensure the Mailprotector solution is ready to scan and protect the tenant domain.

If the domain and users are not configured in the Mailprotector Console, please start with Step 2: Add Users.

You should also have access to the domain's public DNS zone. Changing the MX record is a required step to provisioning Mailprotector. The MX record should be modified before turning on the inbound connector configured in Office 365. View Step 3: Change the DNS MX Records for more information.

Configuring the Connectors

Inbound Connector

The inbound SMTP connector restricts email delivery to Mailprotector's IP addresses. The connector prevents spammers from directly using the Office 365 host address and bypassing Mailprotector's filters.

Read the Office 365 - Inbound Connector knowledge base article for detailed configuration instructions.

Outbound Connector

The outbound SMTP connector directs email from Office 365 through Mailprotector's smart host relay. The relay protects the domain from sending spam if an account is compromised and allows for additional Mailprotector solutions to be applied, such as SecureStore archiving and Bracket email encryption.
