There is a contradiction between some concepts in your question.
Word vs. Print-Quality. We must define what is "print quality".
InDesign to Word, here is another contradiction.
So. "Print quality" as you are asking in a Graphic Design forum has very specific meanings, mainly, correct resolution, no visible compression, embedded color profiles, vector based texts, specific CMYK values corresponding to the color profile and some extra capabilities like defining overprint.
So all that goes to the drain when you embed something inside a Word document.
That is why the process normally is Word (used to write the content of a document) to InDesign (Used to shape that content and prepare it with print quality).
But let me assume the thing you need is "good enough graphics" so people using Word can print in the office some elements designed in Indesign.
Simply export them as PNG with a resolution around 150ppi.
But you can not convert a template made in Indesign to Word.
You need to think in terms of Word, how it works, how it pushes elements or allow to wrap text around them.
So you make some visuals and insert them into Word, either using the Headers and Footers options of the document or inserting them as images and configuring the type of flow they need in the document.
And you need to define margins and columns with the tools Word has for them. And also you need to define the styles of the text using the correct tools.
