The most common culprit behind the New Outlook's startup problems is often the Edge WebView2 component, crucial for rendering the app. Outdated, missing, or corrupted WebView2 files can prevent Outlook from launching correctly. Other factors, such as incompatible add-ins, corrupted app data, or interference from third-party software, can also contribute to the issue.

Troubleshooting Step-by-Step Fixes: Resolving New Outlook Startup Issues

Before diving into solutions, ensure your Windows 11/10 system is up to date via Settings > Windows Update. Updates frequently include vital components and fixes critical for the new Outlook's functionality.

Here's how to troubleshoot and fix your New Outlook app:

WebView2 1. Reinstall/Repair Edge

Windows 11: WebView2 is preinstalled. Repair by downloading the installer from the official Microsoft site and running it as administrator. It will repair or install a fresh copy.

Windows 10: WebView2 often comes with apps that require it. Repair via Settings > Apps > Installed apps > Modify > Repair.

Repair/Reset 2. Repair or Reset New Outlook

If app files are corrupted, repair or reset New Outlook in Settings > Apps > Installed apps. Click the three dots next to Outlook > Advanced options. First, try Repair; then, if that doesn't work, try Reset (which will delete app data).

Note: Resetting will remove your configured accounts and app settings, but your emails stored on the server will remain safe.

WebView2 is a critical component; ensure it's up-to-date to resolve many Outlook issues.
