Users of the Microsoft Edge browser on Windows 10 can now use a wev-based version of Skype calling. Starting today, you can preview the Skype free voice, video and group video calling in the browser.
“We want to make it easy for anyone to connect on Skype,” The Skype team writes in a new post to the Garage & Updates blog. “We know people don’t want to worry about what device the person they want to speak to has close by – they just want Skype to work.”
Starting today, you can use Microsoft Edge to visit Skype for Web,Outlook.com, Office Online and OneDrive and engage in Skype free voice, video and group video calls without first installing a plug-in/extension.
“Skype calls on the web are hassle free,” Microsoft explains, “for the hundreds of millions of you that use Outlook.com every day, to those that visit Skype.com wanting to make a call or anyone preparing a presentation on PowerPoint online; plugin free calling enables quick-fire chat and collaboration, making it easier to get things done together, with anyone, anywhere. No matter where you are, Skype calling on the web is now just a tap away, right there, ready to go.”
For users of Chrome and Firefox, you will still need a plug-in to perform some Skype calls from the browser.
