Skype is always making improvements, such as enhanced quality, better reliability, and improved security. Because we want everyone to experience the best Skype has to offer, it's sometimes necessary to retire older versions of Skype, and Skype enabled devices. Unsupported Skype enabled devices, and platforms may experience problems with calls and chats, lost or dropped calls and instant messages, or could stop working completely.  

Update to the latest version of Skype for your platform. If you're unable to update to the latest version, you may be able to use Skype for Web on some platforms. Learn more about Skype for Web supported browsers.
