A common cause for Outlook startup issues is related to the Edge WebView2 component. This component, built on the Chromium engine, is crucial for rendering content in modern Microsoft 365 apps, including New Outlook. If WebView2 is missing, outdated, or corrupted, the app may fail to launch. Other factors like outdated add-ins, corrupted app data, and third-party software can also contribute to the problem. Let's dive into how to fix it.

Solution 1: Reinstall or Repair Edge WebView2

The first step in troubleshooting is often related to the Edge WebView2 component. This is the primary rendering engine for the New Outlook application, and a corrupted or missing installation can prevent the app from functioning. Here's how to repair it:
WebView2 Runtime

Windows 11: WebView2 is preinstalled. To repair, download the installer from the official Microsoft site. Run the installer as administrator; it will repair or install the component. Optional: For advanced users, removing a specific registry entry (backup your registry first!) may help force a clean reinstall. Navigate to the correct registry key and delete it before reinstalling the WebView2 component.

Windows 10: WebView2 is usually installed with apps that require it. You can repair it via Settings > Apps > Installed apps. Find WebView2 and select Modify > Repair. Restart your computer after repairing or reinstalling, then try opening Outlook again.

Solution 2: Repair or Reset New Outlook

If the issue persists, repairing or resetting the New Outlook app itself can help. Corrupted app files can cause various issues.

To repair or reset the New Outlook app:

1. Press Win + I to open Settings.

2. Go to Apps > Installed apps.

3. Type 'outlook' in the search bar.

4. Click the three dots next to Outlook and select Advanced options.

5. Click Repair first (this attempts to fix the app without deleting data).

6. If Repair doesn't work, click Reset (this will delete app data; your server emails remain safe).

7. Restart your PC and try launching Outlook.

Solution 3: Disable Problematic Add-ins

Add-ins, particularly legacy COM add-ins from the classic Outlook, can sometimes cause conflicts in the new Outlook app. If you have access to the classic Outlook:

1. Type 'outlook' in the Windows Search bar and select Outlook (classic).

2. Go to File > Options > Add-ins.

3. Click Go next to Manage: COM Add-ins.

4. Uncheck any suspicious add-ins.

5. Click OK and close classic Outlook.

6. Try launching the New Outlook again.

Ensure your system is running the latest version of Windows 11/10 for optimal performance.
