If you're experiencing a start loop issue with the new Outlook for Windows and repairing or resetting Outlook doesn't resolve the problem, you can try the following steps to reset the configuration and clear the cache:

1. Close Outlook completely. Make sure it is not running in the background.
2. Press the Windows key + R on your keyboard to open the Run dialog box.
3. Type %localappdata%\Microsoft\Outlook in the Run dialog box and press Enter. This will open the Outlook data folder in File Explorer.
4. In the Outlook data folder, locate and delete all files with the ".ost" extension. These are the cached data files used by Outlook.
5. Close the File Explorer window.
6. Press the Windows key + R again to open the Run dialog box.
7. Type %appdata%\Microsoft\Outlook in the Run dialog box and press Enter. This will open another Outlook data folder in File Explorer.
8. In the Outlook data folder, locate and delete the following files:
   • Outlook.xml
   • Outlook.office365profile
   • Outlook.srs
9. Close the File Explorer window.
10. Restart your computer.

After following these steps, launch Outlook again. It will rebuild the Outlook data files and start with a fresh configuration. This should help resolve the start loop issue you're experiencing.
