Show all folders
The Folder Pane displays all folders in Outlook. If the Folder Pane is minimized, you won’t be able to see your folders. Here’s how to view all of your folders in Outlook.
Expand the Folder Pane to see all of your folders by setting the Folder Pane view, and click View > Folder Pane.
Tip: Click Minimized to minimize the Folder Pane or Off to remove it from the screen.
Note: You can change how Outlook arranges folders by clicking Folder Pane > Options.
Sometimes the Folder Pane inadvertently gets minimized. Or, sometimes you might want to see more of your inbox and temporarily hide the Folder Pane. If your Folder Pane is minimized, here’s another way to see it.
Click the arrow at the top of your Folder Pane to display all folders.
To keep the Folder Pane open and have Outlook show folders the next time you open it, click the pushpin icon . This has the same result as the procedure above.
Tip: Folders that contain subfolders also have an icon next to them. This expands and minimizes the subfolder view. Click the icon to display any subfolders for that folder.
