Hello Alastair,

Office 2016 is under development at the moment. The official Preview is not available to developers.

It is too early to ask such questions, nobody knows the answer.

Where is the 2016 forum now? This link doesn't work for outsiders, http://connect.microsoft.com/office/Feedback

Hello alastair

I don't know if you have done any updates lately but the new version of Office 2016 has the following:

Access, Excel, PowerPoint, Publisher, OneNote, Outlook, Word but it only lasts for 150 days when activated using the key which is in the file name or your Hotmail/Live/Outlook email address.

It also runs excellent on Windows 10 (Build 10162)

Hope this helps you and others out
