Why can’t I highlight words in Microsoft Word?
You can’t highlight Microsoft Word documents on your PC for several reasons. The following are some of the possible causes:
- Compatibility mode – It might be compatible if you’re working with an older version of a Microsoft Word document or a file saved in a different format.
- Document protection – If a document is protected or restricted, it can affect the functionality and appearance of highlights by editing or formatting restrictions.
- Insufficient permissions – If you’re working on a network or shared document and don’t have the necessary permissions to modify the file, you may be unable to highlight it in Microsoft Word.
