Hello Carolyn Cornie,
Thank you for reaching out to the Microsoft Q&A forum! I can understand how confusing it can be when settings change on their own, especially when the help articles you find online don't match what you are actually seeing on your screen.
The reason the help sites haven't been useful is likely because those steps are written for the Windows version of Outlook. Since you are using a Mac, the layout and settings are located in different places.
Here are the two best ways to do this on a Mac:
Method 1: Mac Menu Bar
- Open Outlook and click any email to make the app active.
- In the Mac menu bar at the very top of your screen, click View.
- Hover over Reading Pane and select Hidden (or Off).
Method 2: The Ribbon (Legacy Outlook)
- In the Outlook window, click the Organize tab.
- Click the Reading Pane icon in the ribbon.
- Select Hidden.
I hope this helps you get your inbox back to the layout you prefer. If you encounter any other issues in the future, feel free to come back to the forum.
