Hi,
Thanks for reaching out Microsoft Community, I’m happy to help with your Outlook setup.
Just to clarify, are you using Outlook.com in a browser or the Windows Mail app? The reading pane behaves differently depending on the platform, so knowing that will help narrow things down.
You can avoid the reading pane in Outlook.com, but Microsoft recently changed how it works. The old option to turn it off completely is gone, but you can switch to “Fill Screen” mode, which hides the preview and only opens emails when you click them. It’s a good way to avoid accidentally viewing phishing messages. Unfortunately, this option isn’t available in the Windows app, where the reading pane is always active.
Please let me know if you need clarification, Happy to help!
Warm regards,
Edward
