If you want to see another Outlook folder, such as Calendar, without switching away from one that you already have open, such as Inbox, follow this procedure:
- If one of the two folders is not already open in the main Outlook window, on the Go menu, click Folder List (Folder List: Displays the folders available in your mailbox. To view subfolders, click the plus sign (+) next to the folder. If the Folder List is not visible, on the Go menu, click Folder List.), and then click the folder to display it.
- Right-click a second folder that you want to display, and then click Open in New Window on the shortcut menu.
