Is it possible to specify Exchange version when sending email with PowerShell? - powershell

Question

I am trying to send an email via Exchange using PowerShell. Is it possible to specify what version of Exchange to use? I don't know if Send-MailMessage is the correct function to use either.
The server requires username and password, and should use Exchange2007_SP1.
Running the code below returns "Send-MailMessage: Service Not Available. Closing Channel. Server response 4.3.2 Service Not Available".
So it seems that the server gets this, but rejects it.
The secured server that this runs on, has no direct internet connection, but can reach the Exchange server. Hence, I cannot download and install addons to PowerShell, if that is required.
Any ideas out there? Am I attacking this from the wrong angle?
$sendMailParams = #{
From = 'sender#somemailaccount.com'
To = 'johndoe#someexchangeserver.com'
Subject = 'some subject here'
Body = 'some body here'
SMTPServer = 'exchange.server.com'
UseSsl = $true
Credential = $mailCred
}
Send-MailMessage #sendMailParams```

The reason for this not working in the first place is due to PowerShell policies on the terminal servers. For security reasons, sending mail from PowerShell has been disabled, since you can mail to anyone, from anyone. When you log on to the system in the morning, you get a random terminal server. If I'd been logged on to the same one all the time, it might have been an option to enable it on that specific terminal server. But as it is, it is too open to enable it on all servers, so that's why it is restricted.
If things change in the future, it might be an option to do this.
I know this isn't a direct answer to the question, but it is no longer relevant for me. IT says it isn't necessary to specify Exchange version when sending through PowerShell.
Thanks for all your inputs, folks. You are the best.
