Dear All,

Windows administrators from numerous organizations report widespread account lockouts triggered by false positives in the rollout of a new Microsoft Entra ID's "leaked credentials" detection app called MACE.

These alerts and lockouts began last night, with some admins believing they were false positives as the accounts have unique passwords that are not used on any other sites or applications.

Microsoft Entra ID, formerly Azure Active Directory, is a cloud-based identity and access management service that helps organizations manage user identities and secure access to resources.
