Hi Martyna Redzisz,
Good day.
Thank you for posting to the Microsoft Community. We are glad to assist.
TO restore the default view in the new Outlook, follow these steps:
- Open Outlook on your computer.
- In the app’s ribbon at the top, select the “View” tab.
- In the “Current View” section, choose “Reset View.”
- Confirm by selecting “Yes” in the prompt.
Your Outlook view will now be set to the default. If the app still isn’t how you want it, you can further customize it by clicking “Change View” in the same “View” tab and choosing one of three options: “Compact,” “Single,” or “Preview.”
If you encounter any issues, you can also reset the view using a command in Windows’ Run dialog box. Type the following command and press Enter: outlook.exe /cleanviews.
Additionally, if an add-in is causing the problem, launch Outlook in safe mode by typing outlook.exe /safe in the Run dialog box. Then, click “Reset View” in the View tab. If this brings the view back to the default, your add-ins might be the culprit. In that case, disable all add-ins and enable them one by one to identify the problematic one.
I hope this helps let me know if this is contrary to what you need, I would still be helpful to answer more of your questions .
Best Regards
