Custom actions are not available in the Essentials solution.
If you are a Tenant Admin and need to create a cloud user for a specific domain, you can use the CoreView custom action script below.
Please note:
- You must set the variable as input for the custom action
- You can't change the domain (it's restricted by the script)
Custom action script:
$UserPincipalName = $UPN+'@M365x795031.OnMicrosoft.com'
$PasswordProfile = New-Object -TypeName Microsoft.Open.AzureAD.Model.PasswordProfile
$PasswordProfile.Password = $Password
New-AzureADUser -DisplayName $DisplayName -PasswordProfile $PasswordProfile -UserPrincipalName $UserPincipalName -AccountEnabled $true -MailNickName $UPN
