Solution 1Recommended

Start Office in Safe Mode to Test Add-ins

Running Word or Outlook in Safe Mode bypasses third-party add-ins, which are the most common cause of application freezes during spell checking.

Third-party dictionary, grammar, or integration add-ins can often conflict with the native Office Editor, causing the application to lock up.

1
Open the Run Dialog

Press the Windows key + R on your keyboard to open the Run command window.

2
Launch in Safe Mode

Type 'winword /safe' (for Word) or 'outlook /safe' (for Outlook) into the dialog box and press Enter.

3
Test and Disable Add-ins

Trigger a spelling correction. If the application does not freeze, go to File > Options > Add-ins. Select 'COM Add-ins' next to Manage, click Go, and uncheck third-party add-ins one by one to identify the culprit.

Safe Mode Verified: If the issue disappears in Safe Mode, you can be certain an add-in is responsible, not a corrupted installation.

Frequently Asked Questions

Why does Word freeze only when I right-click a misspelled word?

This specific freeze is usually caused by conflicting third-party grammar add-ins or a corrupted custom dictionary file that fails to load context menu suggestions.

Can a poor internet connection cause the spelling checker to freeze?

No. The built-in spelling and grammar features in Office generally rely on local dictionary files and work offline. A blocked or poor internet service is rarely the cause of this specific freeze.

Will running an Office Repair delete my documents or emails?

No, running an Office Quick Repair or Online Repair only replaces the application's core system files. Your personal documents, emails, and settings will remain completely intact.
