Why is my Word document tracking changes?

Track Changes is a feature built into Microsoft Word that keeps track of all the edits made to your document and lets you make comments. When Track Changes is turned on, the edit you make are highlighted, appearing in different colors or styles to separate them from the original text.

Why is my document not showing track changes?

If “Track Changes” is greyed out in the Word menu bar, then it's possible that the document has been locked from having changes made. In this case, you'll have to first remove document protection before you can track changes in Word.
