select all the emails in her inbox that you want to transfer to your yahoo by holding CTRL then using the mouse, click on each email you want to get. this should highlight the emails. once done, click on forward (this option is usually on the top menu of outlook). all the emails you have selected will be an attachment to one single new mail, and this you can send to your yahoo by just entering your yahoo email address and clicking send.
