I am assuming you meant F17. I was searching for this myself a while 
back and found:
http://askubuntu.com/questions/69349/how-to-change-gnome-shell-calendar-default-application

Basically, doing this:

$ gsettings set org.gnome.desktop.default-applications.office.calendar 
exec thunderbird

will let you use thunderbird when you click on 'Open Calendar' from the 
panel clock.

Interestingly, I assumed that I'd be able to change this from:

gnome-control-center -> Details (under 'Sysytem' section) -> Default 
Applications

...but it doesn't seem to offer that option, although I've installed 
thunderbird-lightning from the fedora repos (as opposed to installing it 
as an add-on in my thunderbird instance).

Not sure if this is a bug with thunderbird-lightning or with 
gnome-control-center.
