You can view your Contacts list from the Contacts screen.
From the left, tap the second icon to get to the Contacts screen. At the top, tap Lync to view just your Lync contacts, or tap iPad to view all your contacts including all your Lync and iPad contacts.
The Contacts list in Lync 2013 running on the desktop is the same list you’ll have in the Lync app. To make changes to your Contacts list, you’ll need to do it from Lync running on your desktop. You can only view your Contacts list from Lync for iPad. You can’t make changes to it from the app.
