In my Office 365 tenant, one of the user changed his password January 5th (I have the proof through an Activity alert I have set sent by Office 365) but the LastPasswordChangeTimestamp  property that I query using PowerShell is still showing the previous date when he changed his password (Sept 24, 2019).

We are using Office 365 alone (our AD is on-premise and fully disconnected).

We have a policy set to have the password expiring after 90 days. The user still have access to his mailbox.

Anybody saw that before? How to fix?
