To reset the view in Outlook to its default settings, follow these steps:
- Open Outlook on your computer.
- In the Outlook ribbon, switch to the “View” tab.
- Click the “Reset View” button.

Your Outlook view will now be set to the default. If you’re still not satisfied with the view, you can also try the following options:
Click “Change View” in the same “View” tab and choose from three options: “Compact,” “Single,” or “Preview.”
Additionally, if you encounter any issues, you can reset the view using a command in Windows’ Run dialog box. Type the following command and press Enter:

This will launch Outlook with the default view. If the problem persists, consider launching Outlook in safe mode to troubleshoot add-ins that might be causing the issue.
