Install Latest Updates

To resolve the Microsoft Outlook 2010 Not Responding error, make sure to install the latest updates for your Windows operating system. Open the Control Panel and navigate to Windows Update to check for any available updates. Keeping your system up to date can help fix bugs and vulnerabilities that may be causing Outlook to freeze.

If the problem continues, try running Outlook in safe mode to see if any third-party plugins or add-ins are causing the error. To do this, press and hold the Ctrl key while opening Outlook. If Outlook opens in safe mode without any issues, you may need to disable or remove any recently installed plugins.

Additionally, check for any corrupted files or settings in your Outlook profile. You can create a new Outlook profile by going to Control Panel > Mail > Show Profiles, and then adding a new profile. Set the new profile as the default and see if Outlook responds properly.
