I have an add-in (dotm template) which is stored in Word's Startup folder. Among other things it contains a customized ribbon.
This works fine, no problems when Word is started from the menu, double clicking a document etc. The add-in is loaded and the customizations in the ribbon are visible.
However if Word is started from VBA within another application (Excel or Access) the customizations in the ribbon do not show. If I check in the Developer tab the Add-in is listed and is selected as well.
Even if I unselected it (unload) and select (load) it again from the interface, the customized ribbon does not show.
This worked fine in Office 2010 with the exact same Excel VBA code and the same add-in.
Why does it not work in Office 2016?
