Email SMTP authentication being deprecated by Microsoft in September 2025

[Sebast1aan]

When setting up email notifications in Argo CD, it currently uses the SMPT protocol according to the documentation.

Microsoft announced that that it will permanently remove support for SMTP AUTH in September 2025.
Will this have immediate impact on email notifications being send via Argo CD?
If yes:

• are there any plans to provide new authentication mechanisms such that email notifications keep on working?
• do we need to list it in the documentation?
