Name:           Export Office 365 MFA status report
Description:    This script exports Microsoft 365 MFA status report to CSV
Version:        2.2
website:        o365reports.com

Script Highlights: 
~~~~~~~~~~~~~~~~~

1.The result can be filtered based on MFA status. i.e., you can filter MFA enabled users/enforced users/disabled users alone. For example using the ‘EnabledOnly‘ flag you shall export Office 365 users’ MFA enabled status to CSV file.
2.Exports result to CSV file. 
3.Result can be filtered based on Admin users.
4.You can filter result to display Licensed users alone.
5.You can filter result based on SignIn Status (SignIn allowed/denied).
6.The script produces different output files based on MFA status. 
7.You can use this script to get users’ MFA status set by Conditional Access.
8.The script can be executed with MFA enabled account. 
9.Using the ‘Admin Roles’ column, you can find users with admin roles that are not protected with MFA. For example, you can find Global Admins without MFA.
10.The script is scheduler friendly. i.e., credentials can be passed as parameter instead of saving inside the script.
