Favorites is the section located at the top of the folder pane and lets you keep frequently used mail folders easily available. You won’t have to scroll through the Folder Pane to find the folder that might be several levels deep within the Folder Pane.
There are several ways to add or remove folders to Favorites. Pick the way that’s most convenient for you.
Click a folder and drag it to Favorites. (You can’t remove a folder this way.)
Right-click the folder you want to add or remove, and then click Show in Favorites or Remove from Favorites.
In the Folder Pane, click the folder you want to add, and then click Folder. In the Favorites group, click Show in Favorites. The ribbon command is highlighted when the selected folder appears in Favorites.
When a folder is added to Favorites, it’s a shortcut to the folder. The actual folder and its content remains at the original location in the folder list. Removing a folder from Favorites doesn’t delete the folder or contents—it removes only the shortcut that appears in Favorites.
By default, when a folder is added to Favorites, it appears at the bottom of the list. To re-arrange the folders, drag the folder to the new position in the Favorites list.
Important: Ensure you remove folders from the Favorites instead of deleting them. When you remove a folder from Favorites, the original folder in the folder list remains. Deleting a folder from Favorites deletes the folder and its contents from Outlook.
