Make changes in a restricted document
When you open a protected document, Word restricts what you can change based on whether the document owner granted you permission to make changes to a specific part of the document.
The Restrict Editing task pane displays buttons for moving to the regions of the document that you have permission to change.
If you do not have permission to edit any parts of the document, Word restricts editing and displays the message, “Word has finished searching the document” when you click the buttons in the Restrict Editing task pane.
Find parts you can edit
If you close the Restrict Editing task pane and then try to make changes where you do not have permission, Word displays the following message in the status bar:
This modification is not allowed because the selection is locked.
To return to the task pane and find a region where you have permission to edit, do the following:
- On the Review tab, in the Protect group, click Restrict Editing.
- Click Find Next Region I Can Edit or Show All Regions I Can Edit.
