I am using Outlook Automation to send emails.
The email address from whom the email is sent seems to be the users
address current on the machine.

Is there any way to change this.
i.e. Mary's machine is sending the email (mary@mycompany.com) but I want
the email to say sent from: salesdept@mycompany.com

I dont see any of the automation properies where you can specify this

Tia
