Sending email to multiple users in BCC field

Question

_{Friday, June 14, 2019 7:50 PM}

I'm trying to use PowerShell to send an Outlook email to a list of email addresses, but I would like them all to be BCC'd so none of the users see that other individuals are being sent the email. The code below works to send the email to 2 users, but I'm having trouble adapting this to BCC the emails rather than include them all in the To field. Any assistance would be greatly appreciated!

$ol = New-Object -comObject Outlook.Application 
$ns = $ol.GetNameSpace("MAPI")
$mail = $ol.CreateItem(0)
[String[]]$Recipient = '[email protected]','[email protected]'
$Recipient | % {$mail.recipients.add($_)}
$ndatetime = Get-Date -Format g
$Mail.Subject = 'Testing' 
$Mail.Body = "Testing"
$Mail.send()

The suggested solution didn't work exactly as written for me, but I was able to adapt it. The following code worked for me:

(get-credential).password | ConvertFrom-SecureString | set-content "C:\documents\password.txt"

$password = Get-Content "C:\documents\password.txt" | ConvertTo-SecureString 

$message = New-Object System.Net.Mail.MailMessage
$message.Subject = "Testing"
$message.Body = "Testing"
[String[]]$BCC = '[email protected]','[email protected]'
$BCC | % {$message.BCC.add($_)}
$message.From = "[email protected]" 

$smtp = New-Object System.Net.Mail.SmtpClient('smtp-mail.outlook.com','587');
$smtp.EnableSSL = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential('[email protected]', $password);
$smtp.send($message)

Just add the list to the BCC field.  There is no other way.

why use an old PS1 method when you can just use the correct Net PowerShell command "Send-MailMessage".

$mailprops = @{
    To = '[email protected]'
    From = "[email protected]"
    Subject = "Testing"
    Body = "Testing"
    BCC = '[email protected]', '[email protected]'
    SMTPServer = 'smtp-mail.outlook.com'
    Port = 587
    UseSSL = $true
    Credentials = New-Object System.Net.NetworkCredential('[email protected]', $password)
}
Send-MailMessage @mailprops
