I don't think Thunderbird will be suitable for this.

You can indeed prepare an email message by passing address, subject, body, attachments etc as command line parameters, but all it will do is assemble a new message using these data and then wait for you to click the Send button.

I don't know for sure if Outlook will be any better suited. I guess it will support scripting, but that would mean you writing the automation script yourself.

I would suspect that if the system is designed to use email to send alerts, it will have the basic email sending capability built in. Look for mentions of "SMTP" in its settings. This is what I have found in devices such as IP cameras which can automatically record when triggered by motion, and then send an email alert. I think you don't need an email client, at least for the sending part.

Thanks for your time but the issue is my Trane Tracer Summit BAS software needs to recognize a profile for it to assign an address for email, then send the alarms. Without an Outlook or other program to create a profile the workstation and Summit software has nothing to recognize so it cannot send email. My pc does not have any mail program at all. I tried to use Thunderbird but it doesn't have the full platform that Outlook must have.

I have found a manual, of sorts: http://www.trane.com/commercial/uploads/pdf/1033/basprc001en_0803.pdf but I can't see any mention of how it uses email.

It's hard to know what they mean by "profile". Unfortunately there is a fair amount of software which offers to use email (e.g. scanners) but is written exclusively for MS email products. However I wouldn't spend money on Outlook until I knew just what the Trane software needs. It appears to be quite old and may not be compatible with current versions of outlook.
