Hi Papoušek Vít,
Thank you for posting this case in the Microsoft Community!
To change the behavior of the delete key in Outlook, you can follow these steps:
- Open Outlook and click on the "File" tab in the top left corner.
- Click on "Options" in the left-hand menu.
- In the Outlook Options window, click on "Advanced" in the left-hand menu.
- Scroll down to the "Outlook panes" section and click on "Reading Pane".
- In the Reading Pane settings, you will see an option for "Single key reading using space bar". Uncheck this option.
- Click "OK" to save your changes.
This should change the behavior of the delete key in Outlook so that it only deletes the immediate text, rather than the entire email.
Please do not hesitate to contact me with any questions or concerns. I look forward to hearing from you.
Please note that our initial response may not always resolve the issue right away. However, with your help and more detailed information, we can work together to find a solution.
