Adding First Name of Recipient for Reply/Reply All in Outlook 2010

Is there a simple VBA code that can be used to always put the "First Name" of the person in the body of a email when replying?

i.e ... a line at the top of the new message that was simply [First Name],

I support a helpdesk and this would save me a tremendous amount of time. I would be okay if it was a reply all scenario and there was more than one name if it just defaulted to the first person in the From field in the original message.  I assume it would leverage the info from the profile in the Global Address Book for my company.

I want it to execute anytime I reply or reply all to any message.

Let me know how complex this might be.

Thanks

Adam
