What's new for business users in Microsoft's Office '16'?Summary: Microsoft is privately testing a technical preview of the next version of its Office client for Windows. Here are a few features expected to be part of 'Office 16.'By Mary Jo Foley for All About Microsoft | September 18, 2014 -- 17:56 GMT (18:56 BST)Microsoft officials have been tight-lipped about what the company plans to deliver in the next version of Office client for Windows, codenamed "Office 16." But a bit of information has begun to trickle out about what looks to be a private "technical preview" of the coming Office suite. This technical preview, which some inside Microsoft also are said to be dogfooding internally, is not the touch-first, Metro-Style version of Office for Windows that some of us Microsoft watchers have been calling "Gemini." Instead, this is the preview of the next version of Office for "desktop" Windows PCs and devices. Tom Warren at The Verge posted on September 18 screen shots that are believed to be from the Office 16 technical preview.
