This issue occurs in Microsoft Skype for Business when you customize the title name of the user interface (UI) through client license configuration in the registry. If the client license state is Lync Basic, the configuration is ineffective, and the value of the LyncName string remains in the original setting.
Note See the "Registry Information" section for information about customizing the title name of the Skype for Business client.
