Some AD accounts have password last set date as 1601-01-01_04:30:00

Some AD accounts have password last set date as 1601-01-01_04:30:00 but the account Last Logon Timestamp is shown in the years 2019, 2020,2021, Any idea about this issue

A value of 1601-01-01 basically means that the timestamp value has not been set. It’s Microsoft’s equivalent of NULL for timestamps.

Hi how we can resolve this Some AD accounts have password last set date as 1601-01-01_04:30:00

To solve it just need to set a password or log in with the user.
