Signing in to Lync for the first time

Important:  If you haven’t used Lync on your desktop computer and this is the first time you’re using Lync, you need to have a Lync account created and a sign-in address. If you don’t know this information, contact your technical support team. You cannot create a new Lync account from the Lync app on the Windows Phone.
