I send out invitations which include a live link to an e-mail .. for example  ..." to make a reservation CLICK HERE: *** Email address is removed for privacy ***

This works easily and when the live link to the e-mail address is clicked on an outlook e-mail form addressed to *** Email address is removed for privacy *** pops up  What i would like to do is fill in the e-mail form that pops up with Subject and some details in the text area.

Does anyone know if this is doable and if so how to do it.

Thanks
