Send-Mailmessage timing out - powershell

Question

I am looking to improve an old batch script and upgrade it to powershell, this is a robocopy batch script and i would like it to send a mail with the logfile attatched when it is finished. i managed to get the drive mappings and robocopy part sorted but im having some issues getting the send-mailmessage part to work
`$SourceFolder = "V:\"
$DestinationFolder = "Y:\"
$Dateandtime = Get-Date -format filedate
$password = XXXXXXXXX
$Subject = "Robocopy Results: Backup USA - NL"
$SMTPServer = "mailserver.domain.com"
$Sender = "backupusr#domain.com"
$Username = "backupusr"
$Recipients = "administrator#domain.com"
$Admin = "administrator#domain.com"
$SendEmail = $True
$IncludeAdmin = $True
$AsAttachment = $False
$Cred = new-object Management.Automation.PSCredential $Username, ($password
| ConvertTo-SecureString -AsPlainText -Force)`
This is the line that causes the script to timeout
Send-MailMessage -SmtpServer $SMTPServer -From $Sender -To $Recipients -Subject $Subject -Body "Robocopy results are attached." -DeliveryNotificationOption onFailure -UseSsl -Credential $Cred
this is the error i recieve
Send-MailMessage : The operation has timed out.
At C:\Scripts\bpcti-robocopy.ps1:113 char:1
+ Send-MailMessage -SmtpServer $SMTPServer -From $Sender -To $Recipient ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.Mail.SmtpClient:SmtpClient) [Send-MailMessage], SmtpException
+ FullyQualifiedErrorId : SmtpException,Microsoft.PowerShell.Commands.SendMailMessage
Any help would be greatly appreciated.

Answer 1

The -Credential parameter takes a PSCredential object. You can use Get-Credential to interactively create one using a username and password combination. More detail here.
Alternatively, as your password is already in plaintext in your script, you can use the process as described here and construct a new PSCredential.
# Convert the plaintext password into a secure string.
$SecurePassword = ConvertTo-SecureString "XXXXXXXXX" -AsPlainText -Force
# Create a new PSCredential using the username and secure string password.
$Cred = New-Object System.Management.Automation.PSCredential ("backupusr#domain.com", $SecurePassword)
Send-MailMessage -SmtpServer mailserver.domain.com -From backupusr#domain.com -To administrator#domain.com -Subject testing -Body "Robocopy results are attached." -DeliveryNotificationOption onFailure -Credential $Cred
Beware that the username should include the #domain.com.
