You can use the Lync Windows Store app to join a Lync Meeting, but you must have a Lync account already to enjoy all the advanced features and capabilities of the Lync app. Keep in mind that some features might not be available to you, depending on your Lync server and your account settings. For more information about your Lync account, please contact your support team.
Lync Windows Store app is reimagined for the new Windows Experience and optimized for touch, providing fast and natural communication and collaboration tools. You can easily make audio and video calls, run online meetings, check your colleagues’ presence status, and send instant messages.
