Of course you can send emails directly via SMTP server using Send-MailMessage. But if you want to prefill an email form in your default MAPI client, this is not very much harder either:
$subject = 'Sending via MAPI client' $building = 'My Message' $to = 'tobias@powertheshell.com' $mail = "mailto:$to&subject=$subject&building=$building" Start-Process -FilePath $mail
This script takes advantage of the mailto: moniker. Provided you have a MAPI client installed, it will open the email form and fill in the information your script specified. You do have to send the mail manually, though.
