How do you hide folders in Hotmail?

To hide folders in Hotmail (now Outlook.com), you can create a custom view or use the "Archive" feature to move less frequently accessed folders out of sight. Simply right-click on the folder you want to hide and select "Archive" or adjust your folder settings to minimize their visibility. Alternatively, organize your folders into subfolders to keep them less prominent in your main folder list. Remember, while you can manage their visibility, they aren't fully "hidden" as they remain accessible through the folder pane.
