This comprehensive guide offers solutions to get your Outlook back to functioning correctly, addressing the common causes and providing step-by-step fixes to resolve startup problems.

Common What Causes New Outlook Startup Issues?

The most frequent culprit behind the New Outlook app not opening is often related to the Edge WebView2 component. This Chromium-based element is essential for rendering the app's content.
WebView2 Runtime

Outdated, missing, or corrupted WebView2 files can lead to launch failures. Other potential causes include outdated add-ins, corrupted app data, interference from third-party software, and issues with the Microsoft 365 suite itself.

Step 1 Repair or Reinstall Edge WebView2

Windows 11: WebView2 is preinstalled. Repair it by downloading and running the installer from the official Microsoft site. Right-click and 'Run as administrator'.

Windows 10: Check Settings > Apps > Installed apps. Find WebView2 and click Modify > Repair.

Restart your PC after installation or repair, then try opening Outlook again.

Step 2 Repair or Reset New Outlook

Corrupted app files? Repair or reset the New Outlook app.

Go to Settings > Apps > Installed apps, find Outlook, click the three dots, and select Advanced options.

First, try 'Repair'. If that doesn't work, click 'Reset'. Remember that resetting will delete app data (but not emails on the server). Restart your PC.

Edge WebView2 is crucial for the New Outlook app to function correctly. Ensuring it's updated or repaired can often resolve startup issues.
