Idea Summary
To align with modern security standards and upcoming changes by major email providers, Oracle APEX should support OAuth 2.0 authenticatio for sending emails via SMTP in Instance Settings. This will enable secure email delivery using providers that are phasing out basic authentication, such as Office 365.

Use Case
APEX applications often rely on outbound email for user notifications, approvals, and system alerts. Currently, these emails are sent using SMTP with basic authentication (username and password), which is increasingly being deprecated across the industry.

For example:

• Microsoft is retiring Basic Auth for SMTP in Exchange Online (O365) by September 2025, requiring OAuth 2.0 instead.
• Other providers like Google Workspace have already enforced similar changes.

Organizations using such providers will face disruptions if APEX does not support OAuth 2.0 natively for email configuration.

Preferred Solution (Optional)

Enhance Oracle APEX Instance Settings to include support for OAuth 2.0 authentication in email configuration inside Instanc Setting.
