To fix the issue, you’ll need to verify and adjust proofing, language, and document-specific settings. One common cause is the use of proofing exceptions, which you’ll check later in this guide. In some cases, proofing exceptions or incorrect language settings may also interfere with the spell checker. Checking these settings can help resolve the issue.
1. Configure the Proofing Language Settings
Configuring the proofing language settings involves selecting the correct proofing language {e.g., English (US) or English (UK)} and ensuring the “Do not check spelling or grammar” option is disabled. These settings allow Word to detect and underline spelling and grammar mistakes, assuming the correct language pack, its associated proofing tools are installed and the document isn’t in a protected state. Note: This method applies to the desktop version of Microsoft Word on Windows. Some features may differ slightly on macOS or Word Online. Note: If some proofing options appear greyed out or unavailable, your organization may have restricted them via group policies. In such cases, contact your IT administrator.
2. Check Proofing Exceptions
Proofing exceptions are document-level settings in Microsoft Word that override normal spelling and grammar checks. These exceptions may apply to individual sections or the entire document and are often enabled unintentionally—especially in files copied from other sources or templates.
Hide errors (e.g., squiggly underlines) without disabling the spell checker entirely.Skip checking specific sections or documents altogether.
If these settings are misconfigured, Word may appear to ignore errors because they’re hidden from view, even though spell and grammar checking remains active in the background. Now, enable global spell check features:
3. Start Microsoft Word in Safe Mode
If the issue persists, it’s likely caused by add-ins, template corruption, or custom settings interfering with the spell checker. Starting Microsoft Word in Safe Mode temporarily disables these elements and helps diagnose whether they are responsible. If the spell checker works in Safe Mode, continue with the steps below to apply a permanent fix. Note: If the spell checker works in Safe Mode, the issue is likely caused by a third-party add-in, corrupted user template (Normal.dotm), or a custom Word setting. Next steps:
To disable add-ins, go to File > Options > Add-ins. At the bottom, choose COM Add-ins from the drop-down and click Go. Uncheck all listed add-ins and click OK.If the issue persists, advanced users can try renaming or deleting the Normal.dotm file to regenerate it. It’s usually located at: C:\Users[YourName]\AppData\Roaming\Microsoft\Templates.
After performing these steps, restart Microsoft Word (or your computer, if needed) and test the spell checker again.
