Does Portal support Microsoft Modern Authentication for email notifications and MFA? I can't find any documentation stating that it does, and when reviewing the configuration for setting up the emailer in Portal, it doesn't appear to be compliant with modern authentication.

With Microsoft (eventually) ending support for legacy authentication, we're going to need Portal to support Microsoft Modern Authentication in order for Portal emails and MFA to continue to function.

We're in the same boat and also looking for an answer to this. Got a Microsoft notification stating support for basic authentication is ending April 30 2026, but Microsoft will gradually start rejecting basic auth submissions from March 1 2026.

They've already pushed back the deprecation timeline as it was originally set to September 2025

I reached out to Esri support and learned there was already an enhancement submitted for this. ENH-000163207

It was submitted in November of 2023, and last updated in June of 2024. Considering it's been over a year since it's been updated, I can only assume that this is very low on the priority list for Esri and that everyone who uses Microsoft as their email platform is going to need to have contingency plans in place for when Microsoft officially deprecates legacy authentication.

I created an ArcGIS Idea to hopefully get some more visibility to this issue. But realistically, I'm expecting anything MS related to break within Portal once MS fully shuts down legacy authentication.
