Product: Microsoft Outlook
Device & OS: Windows
Scenario: Launching or actively using Microsoft Outlook to manage emails.

Solution 1Recommended

Run a Quick Repair for Microsoft Office

Running the built-in Windows repair tool is the most effective way to resolve corrupt application files that cause Outlook to crash unexpectedly.

The Quick Repair option is a fast way to fix common Office application errors locally without needing an active internet connection or reinstalling the entire software package.

Restart Your Computer

Restart your PC to ensure all hidden background Outlook processes are completely closed and system resources are refreshed before beginning the repair.

Open Windows Settings

Click the Start Menu and open 'Settings'. Navigate to 'Apps', then select 'Apps & Features' (or 'Installed apps' if you are using Windows 11).

Modify Microsoft Office Installation

Scroll through the application list to find your specific version of Microsoft Office. Click on it (or click the three vertical dots next to it) and select 'Modify'.

Execute Quick Repair

Select 'Quick Repair' from the prompt that appears and click 'Repair'. Wait for the progress bar to finish, then relaunch Outlook to verify if the error is resolved.

Try Online Repair as a Backup: If the Quick Repair does not fix the problem, repeat the exact same steps but select 'Online Repair' for a more thorough software reset. Keep in mind that Online Repair requires a stable internet connection.

Frequently Asked Questions

What causes Microsoft Outlook to stop working correctly?

This error is typically triggered by corrupted Office installation files, conflicting third-party add-ins, an outdated software version, or a damaged Outlook user profile that forces the app to quit to protect data.

Will running Quick Repair delete my saved emails or contacts?

No. Running a Quick Repair or Online Repair for Microsoft Office only scans and fixes the application's core program files. It will not delete your emails, contacts, calendar entries, or account settings.

How can I check if an add-in is causing the Outlook error?

You can troubleshoot this by launching Outlook in Safe Mode. Press and hold the Ctrl key while clicking the Outlook shortcut. If Outlook opens without the error, go to File > Options > Add-ins to disable any suspicious or recently installed third-party extensions.
