Use Powershell to Find Which Office 365 Users Have MFA Enabled

There are many ways to determine if users have MFA enabled on their Office 365 accounts including viewing MFA status via the Office 365 Admin Portal but in some cases MFA is enabled via Security Groups and the Admin portal will not display if users have MFA enabled or not.
Below are a few different Powershell commands that can be used to report users MFA status.
In order to run these commands you will need to connect to your Office 365 tenant using powershell. Instructions on how to do this can be found here: http://itwalkthroughs.com/knowledge-base/connect-to-office-365-via-powershell-with-mfa-enabled-account/
