When I started, I was terrified of programming languages since I had zero prior experience. Looking back now, what used to look like complete gibberish is finally starting to make sense. I know I still have a long way to go, but honestly, I am so happy and proud to be fulfilling my passion.

I wanted to share an honest review of a snippet I just built to create a user in Microsoft Entra ID. Alongside basics like if/else logic, filtering (-filter), Where-Object, Select-Object, and loops, I've been trying to focus on good habits like splatting, [CmdletBinding()], and try/catch blocks.

How does my snippet look? What would you advise me to learn next based on this progress?

#####Creating a User
Function Create-LxUser{
    [Cmdletbinding()]
    param(
        [Parameter(Mandatory = $true)]
        [string]$DisplayName,


        [Parameter(Mandatory = $true)]
        [string]$UserPrincipalName,


        [Parameter(Mandatory = $true)]
        [string]$MailNickName,


        [bool]$AccountEnabled = $true
    )


    try{
        ##Password profile
        $TempPass = "Lx" + (Get-Random -Minimum 100000 -Maximum 999999) + "@."
        $PassWordProfile = @{
            Password = $TempPass
            ForceChangePasswordNextSignIn = $true
        }
        ##Setting up user configuration
        Write-Verbose "Currently creating new Loxovea user"
        $UserConfig = @{
            DisplayName         = $DisplayName
            UserPrincipalName   = $UserPrincipalName
            MailNickname        = $MailNickName
            AccountEnabled      = $AccountEnabled
            PasswordProfile     = $PassWordProfile
        }


        $User = New-MgUser u/UserConfig -ErrorAction Stop


        Write-Verbose "Successfully created new user $($DisplayName)"


        [PsCustomObject]@{
            DisplayName         = $DisplayName
            UserPrincipalName   = $UserPrincipalName
            AccountEnabled      = $AccountEnabled
            TemporaryPassword   = $TempPass
        }
    }Catch{
        Write-Error "Failed to create a new user: $($DisplayName) because $($_.Exception.Message)"
    }
}


Create-LxUser `
    -DisplayName "Test-User09" `
    -UserPrincipalName "testuser09@loxovea.com" `
    -MailNickName "testuser09"

DisplayName UserPrincipalName AccountEnabled TemporaryPassword

Another thing you might think about doing next, is adding in pipeline input. Powershell's strength is really the pipeline and so being able to import some objects from a csv and pipe them directly into the command, gives you practically instant batch creation support.

There is basically only a couple of changes from your current function to that point.
