About to try the Office 2016 preview - which will be interesting. Have had trouble trying to install power Query for excel - but that is now included so solves that problem.
In the meantime have been looking at embedding word documents - partly because I am now having to report progress in projects in different places so thought embedding a updates and next steps into multiple documents might help - turns out it is complicated and doesn't work well, particularly in my complex filing system - so looking at extending my use of onenote and linked notes in that to see if that will do it.
Will keep you posted about Office 2106 and the onenote expansions.
