Overview

Starting with version 26.1 email sending is supported via Microsoft Graph by introducing the Mail.Send permission in the Service Connections configuration. This enhancement enables applications to send emails over Microsoft Graph using HTTPS instead of relying on SMTP.

This change addresses environments where SMTP cannot be used due to network restrictions, blocked outbound SMTP traffic, mandatory proxy usage, or security policies that disable traditional SMTP authentication. It offers an alternative to the dependency on direct SMTP connectivity, providing a secure and modern solution for sending email in restricted or security-conscious infrastructures.
