outlook classic not responding

The tag 'outlook classic not responding' covers issues where the classic version of Microsoft Outlook fails to open, hangs during profile loading, or becomes unresponsive on Windows 11. Common troubleshooting steps include restarting the application and computer, but persistent problems may require further investigation into profile corruption or add-in conflicts. Users experiencing this issue often see the Outlook splash screen stuck without progress. The tag focuses on the classic Outlook client, not the new Outlook for Windows, and is relevant for Microsoft 365 subscribers and enterprise environments.
