### Description Airflow SMTP notification mechanism to be updated with ability to authenticate using OAuth. ### Use case/motivation Airflow does not currently support OAuth for SMTP. Microsoft is removing BasicAuth as capability from Exchange Online globally this September 2025 (Source: [Microsoft announcement](https://techcommunity.microsoft.com/blog/exchange/exchange-online-to-retire-basic-auth-for-client-submission-smtp-auth/4114750)). This means Airflow users who are also Exchange Online customers will no longer be able to use Airflow to send email notifications. I imagine there's a lot of those. ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
