How to Fix Text Highlighting Not Working in Word

To fix text highlighting not working in Word, first identify the correct account, file, device, or service context. The steps below isolate the cause and apply a result you can verify.

Protect the Document and Check Its Editing State

Start by confirming whether the symptom affects one file, one device, one account, or the service itself. That distinction determines whether the next action belongs in the desktop app, the web portal, or an administrator console.

Quick Word Check

First, run through the Word-specific troubleshooting steps to identify and remove the cause so that Word no longer needs to be started in admin mode. Next, test Word without add-ins, and verify the final state before changing any backup or secondary account.

Why This Can Happen

• The wrong personal, work, school, billing, or administrator account is selected
• A license, permission, connection, file rule, or local setting does not match the requested action
• Cached credentials or an incomplete synchronization or activation state hides the current server status
• The Microsoft service or application requires a more specific control than a generic restart
