Outlook 2003 Signature script

[Eagle11]

Hi,

How can I create signature for all our users once they login?

I have HTML file that sets the CSS and fonts, I want to use this file
in a script and create the signature in outlook 2003.

We are using windows 2003 AD, outlook 2003/2007 and XP pro.
I am already using a script that gets all my AD user info and create
signature using Word, but my manager wants to use HTML code that he
designed.

So can we create a script that uses HTML to produce Signature?

Many thanks
