Test SMTP
Save SMTP settings first, then enter a test recipient and send a test. A successful test confirms that Desk can authenticate and submit mail to the configured server.
Ticket replies
Customer-facing ticket replies use the configured outbound email workflow. Internal Notes are not sent to customers.
