Microsoft announced the integration of Skype in Office Online late last year. So you could collaborate and co-edit documents using the video call and chat service. Starting today you can do the same in OneDrive. The conversations will stay linked to the document-in-progress so you can have all the context and history slapped on for future reference. While Skype is being integrated firmly into online tools to boost interaction, Microsoft has decided to discontinue the Skype for TV app.
