New-MgUser cmdlet to add over 500 external users?

To add over 500 external users using the New-MgUser cmdlet in PowerShell, you can create a script that loops through a list of user details and creates each user. Below is an example script that demonstrates how to achieve this:

# Define the list of external users to add
$users = @(
    @{DisplayName='User1'; MailNickName='User1'; UserPrincipalName='******@external.com'; Password='Password1!'},
    @{DisplayName='User2'; MailNickName='User2'; UserPrincipalName='******@external.com'; Password='Password2!'},
    # Add more users as needed
)

# Loop through each user and create them
foreach ($user in $users) {
    $PasswordProfile = @{ Password = $user.Password }
    New-MgUser -DisplayName $user.DisplayName -PasswordProfile $PasswordProfile -AccountEnabled $true -MailNickName $user.MailNickName -UserPrincipalName $user.UserPrincipalName
}

Notes:

• Ensure that you have the necessary permissions to create users, such as User.ReadWrite.All.
• The Password should meet your organization's password policy requirements.
• You can expand the $users array to include all 500+ users you wish to add.

This script will create each user in the loop by calling the New-MgUser cmdlet with the specified parameters.
