The process facilitates sending email messages through Microsoft’s cloud-based service, even when the sender’s system isn’t directly supported for sending. A common scenario involves devices like printers, scanners, or applications that need to transmit notifications or reports but cannot authenticate directly with Office 365. Configuration allows these devices to leverage the service’s infrastructure to route messages to intended recipients.
This configuration offers several advantages, including centralized email management, improved security, and enhanced deliverability. By utilizing a trusted service for sending, organizations can avoid potential issues with IP reputation and spam filtering. Historically, businesses relied on on-premises servers for this functionality; however, utilizing the cloud-based service offers scalability and reduced maintenance overhead.
