I am working with a corporate client who used Lync on a Microsoft 365 platform. However I work independently and have Microsoft Home and Business installed on my laptop. Is it possible for us to connect on Lync in anyway? Likewise I have a colleague Office for Mac. Are we able to connect using Lync in any way? Thanks Shona

You need to have either on-premises Lync server or an Office 365 subscription to use Lync 2013. Have a look at below article to see what are the options that available

Hi Shona,

You needs to have an O365 Subscription in order to log in to your Lync Client.

Hi,

Agree with the people above.

Microsoft Lync Server is an enterprise real-time communications server. The Lync client is used to connect Lync Server. The Lync client is only meant to be used with a Lync Server (hosted in a corporate environment) or an account hosted on Office 365 with Lync functionality enabled. After you doing that you can create a user on Lync Server and login to Lync Server with Lync client.
