High Volume Email Is Now Available in Exchange Online
Microsoft Launches High Volume Email in Exchange Online for Transactional Messaging Microsoft has made High Volume Email (HVE) generally available in Exchange Online, providing a native, purpose-built solution for organizations to send large volumes of internal transactional and operational emails reliably and securely. HVE uses dedicated accounts separate from user mailboxes, ensuring automated traffic doesn't impact Exchange Online service health or user communication. The service is designed for scenarios like payroll notifications, IT alerts, security advisories, and device-driven workflows. Pricing begins June 1, 2026 at $42 per million recipients. This capability allows organizations to modernize their infrastructure by retiring legacy SMTP relay services and third-party dependencies while maintaining security, compliance, and governance within Microsoft 365.
