Good afternoon,

I have a problem when I connect to Lync using a cell phone, I'd love to give me a hand, checking the Forefront TMG I get these errors. Deputy images.

Hi,

Can you browse the published site directly from an internal client computer as the error message said? How do you configure the publish rule? You could refer to the blog or video below for configuring publish rule of Lync.
