With the SharePoint Connector, embedding documents from Office 365 into Confluence is a matter of seconds using a macro. With this functionality, the user can see the preview and click through ppt(x)-files conveniently without having to open it in SharePoint.
To be able to have a document displayed in full width is already a given in the server version, as is now also a standard for the cloud. Whenever a file is embedded in Confluence, the document will now behave responsively to the width available, e.g. when used in tables with fixed maximum space.
