Recently, Microsoft “enhanced” its Skype for the Web components. In doing so, the company left out Chromebook users from being able to utilize the web-based app. The Skype app for Android still works on ChromeOS, so users can use that if they need to connect to meetings.
However, there’s also another way to accomplish this, proving that there’s literally no good reason why Microsoft is blocking ChromeOS users.
Download and install the User-Agent Switcher Chrome extension.
After the extension is installed, go to the Skype for the Web website, right-click and tell Chrome to run as Microsoft Edge on Windows. The page will refresh and allow you to use Skype in the web browser.
