How does it work?

1. When a user in your Microsoft 365 or Office 365 organization dials and sends a message, the message is diverted to the e-securemail service using a connector and a mail flow rule (also called a transport rule) that you create.

2. e-securemail accepts the message and performs anti-spam and antivirus filtering. The service also adds a custom header to the message to indicate that the message has been processed.

3. e-securemail routes the message to Microsoft 365 or Office 365. A connector you create accepts incoming messages from the e-securemail service.

4. Microsoft 365 or Office 365 sends the message filtered with Microsoft 365 and e-securemail to the original recipients.
