Powershell send-mailmessage - email to multiple recipients

Question

I have this powershell script to sending emails with attachments, but when I add multiple recipients, only the first one gets the message. I've read the documentation and still can't figure it out. Thank you

$recipients = "Marcel <marcel@turie.eu>, Marcelt <marcel@nbs.sk>"

Get-ChildItem "C:Decrypted" | Where {-NOT $_.PSIsContainer} | foreach {$_.fullname} |
send-mailmessage -from "primasfrb@nbs.sk" `
            -to "$recipients" `
            -subject "New files" `
            -body "$teloadmin" `
            -BodyAsHtml `
            -priority  High `
            -dno onSuccess, onFailure `
            -smtpServer  192.168.170.61

Answer 1

$recipients = "Marcel <marcel@turie.eu>, Marcelt <marcel@nbs.sk>"

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

[string[]]$recipients = "Marcel <marcel@turie.eu>", "Marcelt <marcel@nbs.sk>"

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

$recipients = "Marcel <marcel@turie.eu>", "Marcelt <marcel@nbs.sk>"

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