Powershell script for new account creation - reset password, send email and add to group

Hello, I'm looking to optimize and finish one of our scripts following need: Either on the event AD account creation or once per day with a search filter all new accounts need to: * Reset a password * add to a group * send an email to the new user. Accounts are created by an external system, so account creation is NOT needed. Just that the accounts are provisioned with a temp password which we don't know. And we would like to send a welcome email with a PDF attached to the newly created accounts. The trigger either being the Active directory account creation or in the morning with a scheduled task emailing all accounts created D-1 We have a basis, that you can use (or not): ##Beginning of functions Function Send-Email { Param ($Email, $Credential,$attachment) $From = "Hello@[login to view URL]" $subject = "Welcome to CompanyX" $SMTPServer = "[login to view URL]" $SMTPPort = "587" ### Beginning of email body $Body = "Hello New user!,<br><br>" $Body += "Welcome to CompanyX! <br><br>" $Body += " This email will help you log in to Workday and Azure update your personal information before you start. <br><br>" $Body += "Step 1. Enter your username (username)<br><br>" $Body += "Step 2. Enter your password $UserPassword <br><br>" $Body += " Please refer to the attached PDF for more information <br><br>" $Body += "<br><br>" $Body += "Looking forward to see you around,<br><br>" $Body += "CompanyX Corporate " ### End of email body Send-MailMessage -from $From -to $Email -Subject $subject -BodyAsHtml $Body -Attachments $attachment -SmtpServer $SMTPServer -Port $SMTPPort -Credential $Credential -UseSsl } ### End of Functions ##### Beginning of main function $When = ((Get-Date).AddDays(-1)) $UserName = "hello@[login to view URL]" #Gmail username which is used for sending an email $Password = Get-Content "C:\CareBears\[login to view URL]" | ConvertTo-SecureString #Reading a secure password from file and reversing it back into a secure string object $Credential = New-Object -TypeName [login to view URL] -ArgumentList ($UserName, $Password) #PSCredential for send-mail message cmdlet $Attachment = "C:\CareBears\[login to view URL]" #PDF sending as an attachment with email ### Not finished ---- WIP ### $UserPassword = Get-Random -maximum 20000 -Minimum 100 ### $UserPassword = "@" + "user" + $[login to view URL]() ### $UserPrincipalName = ($[login to view URL] + ”@[login to view URL]”) foreach ($EmailAddress in Get-ADUser -filter {(whencreated -ge $When)} -Properties emailaddress | Select -ExpandProperty emailaddress) #Iterating over each email of users { Send-Email -Email $EmailAddress -Credential $Credential -attachment $Attachment Write-Host "Email sent: $EmailAddress" } ### End of main function
