Powershell - sending an outlook message with attachement via powershell (January 23, 2022)-CodePudding

I tried to send an email with attachement to outlook (365) via powershell, like posted in this scriptlet:

$SmtpServer = "smtp.office365.com"
$SmtpPort = 587
$smtp = New-Object System.Net.Mail.SmtpClient($SmtpServer,$SmtpPort)
$MailMessage = New-Object system.net.mail.mailmessage
$attfile = "C:\temp\test.txt"
$attatchment = New-Object System.Net.Mail.Attachment($attfile)
$smtp.Host = "smtp.office365.com" #DNS oder IP
$MailMessage.From = "test***@outlook.de"
$MailMessage.To.Add("test***@outlook.de")
$MailMessage.Subject = "PowerShell Email with attatchemnt"
$MailMessage.Body ="This is a email from powershell with attatchments"
$MailMessage.IsBodyHtml = $false
$MailMessage.Attachments.Add($attatchment)

#mit Authentifizierung beim Mail Server (ohne einfach weglassen)
$SmtpUser = New-Object System.Net.NetworkCredential
$SmtpUser.UserName = "test***"
$SmtpUser.Password = "*****"
$smtp.Credentials = $SmtpUser
$smtp.Send($MailMessage)

Completed with the according real credentials, I got the followin error message:

Ausnahme beim Aufrufen von "Send" mit 1 Argument(en): "Fehler beim Senden von Mail." In Zeile:1 Zeichen:1

$smtp.Send($MailMessage)

    CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    FullyQualifiedErrorId : SmtpException

Any Hints, how I can get it run and send mails with attachement via a powershell script?

Kind regards,

Oliver

try this:

# Get the credential
$credential = Get-Credential
## Define the Send-MailMessage parameters
$mailParams = @{
    SmtpServer                 = 'smtp.office365.com'
    Port                       = '587' 
    UseSSL                     = $true
    Credential                 = $credential
    From                       = '[email protected]'
    To                         = '[email protected]', '[email protected]'
    Subject                    = "SMTP Client Submission - $(Get-Date -Format g)"
    Body                       = 'This is a test email using SMTP Client Submission'
    Attachment                 = 'C:\Test.txt' # Here you can change your attachment
    DeliveryNotificationOption = 'OnFailure', 'OnSuccess'
}

## Send the message
Send-MailMessage @mailParams

Your code worked for me, except that I had to enable ssl.

Maybe add $smtp.EnableSsl = $true

Wouldn`t it be better to use MailKit as recomended here? https://github.com/dotnet/platform-compat/blob/master/docs/DE0005.md
