Windows – Use Office 365 account to login to Windows 10

I think I have it, or at least I have enough to figure out what I need.

Get-MsolUser -userprincipalname user@domain.org | select DisplayName, LastPasswordChangeTimeStamp,@{Name=”PasswordAge”;Expression={(Get-Date)-$_.LastPasswordChangeTimeStamp}}

The result looks like this (date and time format will match your computer's):

DisplayName    LastPasswordChangeTimestamp PasswordAge
-----------    --------------------------- ----------- 
User, Name     09-Mar-16 5:48p             42.22:34:10.6964630

.

In order to see all users whose passwords are older than 30 days, use this.

Get-MsolUser -All | select DisplayName, LastPasswordChangeTimeStamp,@{Name=”PasswordAge”;Expression={(Get-Date)-$_.LastPasswordChangeTimeStamp}} | where {$_.PasswordAge -gt “30”} | sort-object PasswordAge -descending

It will list all of the users with passwords older than 30 days and sort the list by the password age.

I hope this helps others as well.

Add the following registry key: HKCU\SOFTWARE\Microsoft\Office\16.0\Common\Identity\EnableADAL=0

This disables Modern Authentication on your home computer, which is what is causing your home Office/Outlook to log in all together in one shot.
