Teamwork and document collaboration are easier than ever with Skype in Office Online.
When someone is editing with you in Office Online (Word, Excel, PowerPoint, or OneNote), click the Chat, button to open the chat pane.
Type in the box at the bottom of the pane to kick off the conversation. Everyone who has signed in as an Office 365 subscriber will see your message and be able to respond.
If you use Skype on your mobile device or web browser, you'll be able to participate in the chat, even when you're away from the document. The name of the chat is the name of the file.
Note: You might be editing with people who don't have an Office 365 subscription. If they have a Skype account they can participate in the chat on their device or a separate browser window. But they won't have a chat pane next to the document when they're in Office Online.
