You can pin important contacts to your homescreen, so their information will be right there whenever you sign in to your phone. Here’s how:
In Skype for Business (Lync), tap the contact listing for the person you want to add to your homescreen.
Tap the Pin icon in the application bar at bottom of the screen. Skype for Business (Lync) will take you to the location on the homescreen where the contact’s tile will now be displayed.
