Outlook does not start: Crashes, Freezes or is not responding

Are you facing startup issues with Outlook? Does it crashes or shows not responding? If yes then you are at right place. Today we will see how we can fix these common outlook errors, so let’s get started:

Fix 1: Open Outlook in Safe Mode

If recently Microsoft Outlook was working fine and you have made no changes to your configured account then I would recommend you to test the outlook by running it in the safe mode. When we start outlook in safe made then it will not load certain or all add-ins, reading pane is also turned off and also it will not load several settings. This might solve your issue of Outlook is not responding or Outlook does not start.

How to Start Outlook in Safe Mode

  • Hold CTRL: Hold the Control Button (CTRL) of your keyboard and then click on Outlook icon on your Taskbar, Desktop or start screen. When you do this, outlook will ask if you want to start outlook in the safe mode. You can use this easy method to start Outlook in safe mode in any of the Windows Operating system and in all versions of Outlook.

If Starting the Outlook resolves your problem of Outlook is not responding then most probability the problem is caused by the outlook add-ins or by outlook setting. If Outlook still does not start then follow other methods given below. If starting outlook in safe mode also does not work for you then I would recommend you to scan your Outlook data files, there might be corruption in the PST or OST file.

If Outlook works as expected in the Safe Mode then you will need to disable the add-in that is causing the problem with Outlook. Run Outlook in safe Mode à File Menu à Options à Add-ins à Check if add-ins are listed there –> Uncheck those add-ins –> Save the settings –> Restart the Outlook. Hope this time it will definitely work for you.

Fix 2: Update your Outlook to the latest version

Check if you are using the updated version of the outlook. Sometimes the bug that is causing you the problem is fixed in the recent updates. You update if you are not using latest version of the outlook. Outlook 2007 and Outlook 2010 are now not supported by Windows 10 operating system and might cause compatibility issues.

Fix 3: Try Recreating your Email Profile

If running outlook in safe mode and updating outlook to latest version does not fix your problem then try this fix.

If your mail profile is corrupted or damaged then also Outlook will not start or Outlook will not respond. You try recreating your profile. You can recreate your profile from the Mail Profile option in Control Panel.

  • Download and Install Inbox Repaid Tool developed by Microsoft
  • Browse the PST file and click on Start button.
  • Click on Repair if the tool finds some corruption errors in the data file.
