Red Hat SSO - Deprecation of basic authentication in Microsoft Exchange online

Solution In Progress - Updated -

Issue

Starting on January the 1st, 2023, Microsoft has announced they will remove the ability to use Basic authentication in Exchange Online for Exchange ActiveSync (EAS), POP, IMAP, Remote PowerShell, Exchange Web Services (EWS), Offline Address Book (OAB), Autodiscover, Outlook for Windows, and Outlook for Mac in 2023. They're also disabling SMTP authentications in all tenants where it's currently not being used.

This change requires customers to migrate from/update from applications or services using basic authentication towards using Modern Authentication (OAuth 2.0 token-based authorization), more details can be found here:

Emails are sent from Red Hat SSO using SMTP servers, among which there could be also Microsoft Exchange.
From Email Configuration, it does not seem possible to provide an authentication method different from Basic Authentication with Username and Password.

Is there any planned version of RH SSO that fulfills the capacity of sending email using oauth2 authentication?
