i've done the recip mod and everything works except my email program (ms outlook) will not take the mailto link

what could i change in this to make it work ?

ID $link->{ID} <input TYPE=CHECKBOX NAME="delete" VALUE="$link->{ID}"></td><td bgcolor="#ffffff">
$link->{Title}: <a href="$url" target="_new">$url</a></td><td bgcolor="#ffffff"> - is not linking back
</td><td bgcolor="#ffffff"><a href="mailto:$link->{Contact_Email}?subject=Unable to verify reciprical link?body=$body">Send Email</a></br></td></tr>
