You can suggest, but not require, that users open a document as read-only (read-only: A setting that allows a file to be read or copied, but not changed or saved. If you change a read-only file, you can save your changes only if you give the document a new name.). If a user opens the document as read-only and changes it, that person can save the document only by giving it a different file name.
- On the Tools menu, click Options.
- Click Security.
- Select the Read-only recommended check box, and then click OK.
- Click Save.
