question

Hi @Jhon-5981,

To delete users in bulk, you can follow below steps:

• Navigate to Azure AD B2C > Users > All Users > Bulk Operations > Download Users. This will download a list of all users in the B2C tenant with their original UPN, Display name, Mail, AlternateEmailAddress and so on in a CSV file.
  

• Navigate to Azure AD B2C > Users > All Users > Bulk Operations > Bulk Delete and download CSV file.
  

• From the file downloaded in step 1, copy the UPNs of the users that you want to delete and paste in the file downloaded in step 2, as shown below:
  
  

• Navigate to Azure AD B2C > Users > All Users > Bulk Operations > Bulk Delete and upload the updated file.
  

• Type 'Yes' to continue and click on submit.

Note: This will soft delete all the users listed in the uploaded file. Which means the users will be moved to Deleted users and then gets hard/permanently deleted automatically after 30 days. If you want to permanently delete the users before 30 days, you'll have to manually delete the users from the Deleted users blade.

Hi Aman,

thanks for your answer. But i'm looking for more to use power-shell. The answer which you have is already known.

Hi @Jhon-5981 Please find below the script for this purpose:

 Connect-MsolService #sign-in using Global Admin of your B2C tenant. User should be Member of the tenant and not signed-up or guest user.
 $users = import-csv C:\temp\users.csv
 foreach ($usr in $users)
 {
 Remove-MsolUser -UserPrincipalName $usr.upn -Force
 }

Below is how the user.csv file looks:
