Lync Online provides the Lync Admin Center (LAC), a dedicated control panel, to manage Lync settings. To open it, access the Office 365 portal and select Service settings, Lync, and Manage settings in the Lync admin center, as shown in the following screenshot:

LAC, if you compare it with the on-premises Lync Control Panel (or with the Lync Management Shell), offers few options. For example, it is not possible to create or delete users directly inside Lync. We will see some of the tasks we are able to perform in LAC, and then, we will move to the (more powerful) Remote PowerShell.
