Customise Touch Bar in Microsoft Office 2016 The February 2017 updates for Microsoft Office 2016 include Touch Bar support on the new MacBook Pros. But the defaults aren't very usable, and I can't find an option to customise the Touch Bar layout as is found on other apps with TouchBar support. Is there any way to customise the Touch Bar in Office 2016?
There is not an option at this point in time. 
As an office insider, I recently sent a feature  request to them. If you'd like to send a feature request, just click the :) in the top right corner and go from there.
