How do I enable "Add External Users" box?

[rken]

Hi Alfresco Users!

I am having a problem with a new install of Alfresco

I do not see the "Add External Users" box when adding users to a site and am therefore unable to do so

I have configured outbound smtp aswell as put in notification.email.siteinvite=true into my global properties, restarted Alfresco and it doesnt appear

What am I doing wrong?

How to I get this box to appear?

Thanks in advance
