Word provides sharing and review controls for teams working on a common document. Select Share on the ribbon or under File, upload to OneDrive when prompted, and enter the collaborators. A message can explain what they should review before the invitation is sent.

Combine Shared Editing with Change Review in Word

During joint editing, participant names and colored flags help show who is working and where. When changes need formal review, enable Track Changes on Review. Move through the marked edits and select Accept to retain a change or Reject to remove it from the document.
