How to attach a file to an email with PowerShell

问题

I have written a PowerShell script that will create an email, however I can't seem to attach a file. The file does exist and PowerShell can open it, Could anyone tell me what I'm doing wrong?

$ol = New-Object -comObject Outlook.Application 
$message = $ol.CreateItem(0)
$message.Recipients.Add("Deployment")  
$message.Subject = "Website deployment"  
$message.Body = "See attached file for the updates made to the website`r`n`r`nWarm Regards`r`nLuke"

# Attach a file this doesn't work
$file = "K:\Deploy-log.csv"
$attachment = new-object System.Net.Mail.Attachment $file
$message.Attachments.Add($attachment)

If you are on PowerShell 2.0, just use the built-in cmdlet Send-MailMessage:

C:\PS>Send-MailMessage -from "User01 <user01@example.com>" `
                       -to "User02 <user02@example.com>", `
                           "User03 <user03@example.com>" `
                       -subject "Sending the Attachment" `
                       -body "Forgot to send the attachment. Sending now." `
                       -Attachment "data.csv" -smtpServer smtp.fabrikam.com

If you copy/paste this watch out for the extra space added after the backtick. PowerShell doesn't like it.

I got the above to work by removing the line

$attachment = new-object System.Net.Mail.Attachment $file

and changing

$message.Attachments.Add($attachment)

$message.Attachments.Add($file)

While the solution provided by @Keith Hill would be better, even with a lot of goggling I couldn't get it to work.

This worked for me using powershell-

Define Variables:

$fromaddress = "donotreply@pd.com" 
$toaddress = "test@pd.com" 
$Subject = "Test message" 
$body = "Please find attached - test"
$attachment = "C:\temp\test.csv" 
$smtpserver = "mail.pd.com"

Use the variables in the script:

$message = new-object System.Net.Mail.MailMessage 
$message.From = $fromaddress 
$message.To.Add($toaddress)
$message.IsBodyHtml = $True 
$message.Subject = $Subject 
$attach = new-object Net.Mail.Attachment($attachment) 
$message.Attachments.Add($attach) 
$message.body = $body 
$smtp = new-object Net.Mail.SmtpClient($smtpserver) 
$smtp.Send($message)

You can use send-mailmessage or system.net.mail.MailMessage to accomplish it. Interestingly, there is a significant execution time difference between the two approaches. You can use measure-command to observe the execution time of the commands.

I have experienced such problem, (windows 10 / PS 5.1) My SMTP is not authentified or secure ... I have to finish by this line "MyAttacheObject.Dispose()" ... / and finally that's work :!

$smtp = new-object Net.Mail.SmtpClient($smtpserver) 
$attach.Dispose()

this is my code with two attachments :

# Email configuration NO AUTH NO SECURE
$emailHost = "smtp.bot.com"
$emailUser = ""
$emailPass = ""
$emailFrom = "myemail@bot.com"
$emailsTo=@("toyoumylove@bot.com","toyoumybad@bot.com")
$emailSubject = $title
$emailbody=$body
$attachment1 = @($PATh+$outFile) 
$attachment2 = @($PATh+$inFile) 
#End of parameters

$msg = New-Object System.Net.Mail.MailMessage
$msg.from = ($emailFrom)
    foreach ($d in $emailsTo) {    
    $msg.to.add($d)
    }
$msg.Subject = $emailSubject
$msg.Body = $emailbody
$msg.isBodyhtml = $true   

$att = new-object System.Net.Mail.Attachment($attachment1)
$msg.Attachments.add($att)
$att = new-object System.Net.Mail.Attachment($attachment2)
$msg.Attachments.add($att)
$smtp = New-Object System.Net.Mail.SmtpClient $emailHost
$smtp.Credentials = New-Object System.Net.NetworkCredential($emailUser, $emailPass);
  $smtp.send($msg)
  $att.Dispose()
