Finalize and Protect a Document
Finalize the document
When a document is marked as final, typing, editing commands, and proofing marks are disabled or turned off and the document becomes read-only. The Mark as Final command helps to communicate that the shared document is a completed version as well as preventing reviewers or readers from making inadvertent changes to the document
- Go to File tab > click Info > click Protect Document button
- Select Mark as Final to make the document read-only
