Could anyone suggest a way for this:
--------------------------------
* I receive an email with a sender's phone number

* When the email is open for reading in outlook 2003 the phone number is required to automatically
change to a hyperlink (On Load or Button Click!). This hyperlink would point to a website with the
phone number in the query string.
--------------------------------

I tried designing a Message form and publishing it
however could not figure out the right way.

Would really appreciate!

Thanks
