UC, Skype for Business, Communicate with Skype Users with Skype for Business
On this page, you can learn how to use instant messaging, audio calls, and presence information to communicate with Skype users while using Microsoft Lync (and vice-versa).
NOTE: At this time, Lync-Skype calls must be only one party to one party. Lync-Skype conference calls and meetings will not work.
NOTE: Lync-Skype video calling is not yet available from Microsoft.
If you use an email address and password to access services such as Microsoft OneDrive storage technology, Windows Phone, the Microsoft Xbox LIVE online game service, and the Microsoft Outlook messaging and collaboration client (as well as (previously) Microsoft's Hotmail web-based e-mail service or Windows Live Messenger), you already have a Microsoft account (MSA (external link)) (previously called Windows Live ID). If you also have a Skype account, it's easy set up single sign-on to access a variety of additional applications and services, including Lync-to-Skype voice calls, etc.
To set up a Microsoft account, see the Microsoft account sign-up page at http://go.microsoft.com/fwlink/p/?LinkId=306061. (external link)
If Skype users sign in to Skype with a Microsoft account (MSA (external link)) (previously called Windows Live ID), they may use Skype to communicate with their non-Skype contacts who are using Lync (and vice-versa).
NOTE: Be sure to link your Skype account to an MSA. (external link) A Skype account that is not linked to an MSA will not be able to communicate with Lync users.
You can find out if your Skype and Microsoft accounts are already linked by checking https://secure.skype.com/portal/account/settings (external link):
