Adding "From" email address to send mail using adobe acrobat

Hello,
 
We have an email address that we use to send and received faxes. All the employees in the department has access to the mailbox so they use this email address as the primary email for Microsoft Outlook. I have written a toolbarbutton that displays the box where they enter the fax number the document is being sent to, and other important information. I'm trying to change the way they use outlook. So, instead of using outlook for this email, I want them to use outlook for their email and the fax email account will be used as a proxy. Now, my question is: is their a way in Acrobat JS to supply the "From" email account like there's for "To" using "cTo: "? The only reason i need to do this is there's only one email account that has permission to send fax. If anybody could help me with this then it would be great.
 
Thank you.
