OAuth for PRTG SMTP E-Mail Delivery
As a PRTG Network Administrator responsible for maintaining critical IT monitoring, I need PRTG to support OAuth 2.0 authentication for SMTP email notifications, so that we can continue receiving critical monitoring alerts after Microsoft retires Basic Authentication for SMTP AUTH in Exchange Online.
Business Impact:
Microsoft has announced the permanent removal of Basic Authentication for Client Submission (SMTP AUTH) in Exchange Online, with the retirement process beginning March 1, 2026, and completing by April 30, 2026. Without OAuth support in PRTG, our organization will lose all email notifications from our monitoring system, severely impacting our ability to respond to critical infrastructure issues.
Currently, we've successfully migrated all our other applications to modern authentication methods, but PRTG remains the only application we cannot transition due to the lack of OAuth support for SMTP. This creates a significant security vulnerability and compliance risk in our environment.
Implementation Requirements:
- Support for Microsoft 365 OAuth 2.0 authentication for SMTP email delivery
- Integration with Microsoft Azure application registration
- Secure token management and refresh capabilities
- Simple configuration interface in the PRTG notification delivery settings
This feature is critical for our continued use of PRTG, as email notifications are essential to our monitoring workflow.
