Password Spray Alerts on Autopatch configured accounts
We have had several alerts over the last month related to these accounts created by enrolling and setting up Windows Autopatch in intune

We have azure sentinel configured:

We don't have these accounts excluded from Multifactor authentication. Not sure if they need to be. But since these accounts were created when we enrolled in Autopatch, and don't have the passwords but these accounts have the following azure roles: Intune Administrator, Security Reader and User Administrator, I am concern that these account are getting hit with password spray activity?
Should the be happening?

Hi LMSCloudadmin,
As you have done already; opening a support case for the Windows Autopatch Service Engineering team to investigate is the best course of action here.
I would also suggest taking a look at What's New in Windows Autopatch - New Feature: Tenant Management Blade - Microsoft Community Hub as the tenant access model used by Windows Autopatch has changed. The Service accounts are to be removed and replaced with a new First party enterprise application.
Regards,
Richard
