Microsoft announced the addition of Skype document chat to Office Online. It’s avaialble when you collaborate with others in real-time in Word or PowerPoint.

To use it, click the Chat button. You can continue chats after leaving the document via Skype from your desktop computer or phone.

“The Office Online real-time co-authoring feature makes it easy for you to work together with others on a document from your browser,” the company says. “Whether you are putting the final touches on a contract with your business partner or collaborating on an essay for a school project, Office Online lets you work seamlessly with others no matter where they are.”

This is rolling out over the coming weeks at office.com.

Last week, Microsoft announced that the next version of Lync will become Skype for Buisness, which the company says brings together “the familiar experience and user love of Skype with the enterprise security, compliance, and control from Lync to create the most loved and trusted communications platform for doing things together.”

The company also announced the beta launch of Skype for Web, which lets you use Skype from your browser.
