Dear Margret Bechert

Thank you for reaching out to the Microsoft Q&A Community. I understand you are having a problem with the New Outlook app not opening, even though you can access Outlook on the web. I am happy to assist you. Please try the following steps : 

1. End Outlook Processes 
   • Open Task Manager (Ctrl + Shift + Esc), locate any Outlook.exe or related Office processes, select them, and click End Task. 
2. Repair or Reset New Outlook App 
   • Go to Settings > Apps > Installed Apps, find Outlook (New), select Advanced Options, then choose Repair. If that fails, choose Reset. 
3. Update Windows and Office 
   • Install all pending Windows updates. Open any Office app, go to File > Account > Update Options > Update Now. 
4. Reinstall or Repair WebView2 Runtime 
   • New Outlook depends on WebView2. Download the Microsoft Edge WebView2 Evergreen Standalone Installer from Microsoft and run it as administrator. 
   • See : Introduction to Microsoft Edge WebView2 - Microsoft Edge Developer documentation | Microsoft Learn 
5. Sign Out and Sign Back In 
   • If the app partially loads, go to Settings > Accounts, sign out, then sign back in with your Microsoft account. 
6. Disable Compatibility Mode 
   • Right-click the Outlook shortcut > Properties > Compatibility tab, ensure Run this program in compatibility mode is unchecked. 
7. Create a New Outlook Profile 
   • Open Control Panel > Mail > Show Profiles, click Add, create a new profile, and set it as default.
