2. Click on the "File" menu at the top of the screen.
3. Select "New Folder" from the drop-down menu.
4. In the "New Folder" window, enter a name for your new folder in the "Name" field.
5. Choose a location for your new folder by selecting a mailbox from the "Location" dropdown menu. You can choose to create the folder in the current mailbox or in a different mailbox.
