Powershell send-mailmessage - email to multiple recipients

$recipients = "Marcel <[email protected]>, Marcelt <[email protected]>"

is type of string you need pass to send-mailmessage a string[] type (an array):

[string[]]$recipients = "Marcel <[email protected]>", "Marcelt <[email protected]>"

I think that not casting to string[] do the job for the coercing rules of powershell:

$recipients = "Marcel <[email protected]>", "Marcelt <[email protected]>"

is object[] type but can do the same job.

Just creating a Powershell array will do the trick

$recipients = @("Marcel <[email protected]>", "Marcelt <[email protected]>")

The same approach can be used for attachments

$attachments = @("$PSScriptRoot\image003.png", "$PSScriptRoot\image004.jpg")

You must first convert the string to a string array, like this:

$recipients = "Marcel <[email protected]>,Marcelt <[email protected]>"
[string[]]$To = $recipients.Split(',')

Then use Send-MailMessage like this:

Send-MailMessage -From "[email protected]" -To $To -subject "New files" -body "$teloadmin" -BodyAsHtml -priority High -dno onSuccess, onFailure -smtpServer 192.168.170.61

To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom
