How to use the Review Mode in Microsoft Word

Instead of full edit control you are allowed to add suggestions to the document in the form of comments or tracked changes in Review Mode.

Document owners or other collaborators who have full edit permissions will then need to approve the incorporation of any suggested changes to the document.
