Why can I no longer make audio or video calls on Skype for Outlook.com on Chrome on Windows?
Skype for Outlook.com uses a plugin to enable audio and video calls. Recently, Chrome has discontinued support for the plugin technology Skype for Outlook.com uses. We are currently working on rolling out a solution for Chrome that will address these issues. In the meantime, simply visit Outlook.com from Internet Explorer or Firefox to make calls from Skype for Outlook.com.
