A family of Microsoft word processing software products for creating web, email, and print documents.
In order to protect only specific portions of the document requires inserting Section Breaks. To apply the protection don't use the tool on the Developer tab. Instead;
- Go to Tools> Protect Document.
- Check the Protect document for box
- Choose the Forms option
- Click the Sections button then clear the checks for the Sections to not be protected
Tip: Unfortunately, the Protect Document dialog window doesn't allow accessing the document in the background. In longer, more complex documents it's a good idea to first make a note of which Sections to leave unprotected.
