Me_RIT,
you can run to run this PS CMDLETs to figure pull out a report on the users already encrolled for MFA.
Connect-MsolService
Get-MsolUser -All | select DisplayName,BlockCredential,UserPrincipalName,@{N="MFA Status"; E={ if( $_.StrongAuthenticationRequirements.State -ne $null){ $_.StrongAuthenticationRequirements.State} else { "Disabled"}}}
Rest, you can create a script and based on this report, you can generate an email notification to get the admin team notified.
Hope this helps.
