See below steps. Follow the step that applies to the type of folder you
would like to add.
Step 1: Right-click the folder you want to add, and then on the shortcut
menu (shortcut menu: A menu that shows a list of commands relevant to a
particular item. To display a shortcut menu, right-click an item or press
SHIFT+F10.), click Add to Favorite Folders.
Step 2: If you are in the Mail pane, you can quickly add a folder to
Favorite Folders by clicking the folder you want to add, and then dragging it
to Favorite Folders.
Repeat the step for each folder that you want to add. Folders must be added
individually to Favorite Folders.
I hope this helps.
