Windows Live Mail and Office 365

For years, I used Windows Live Mail and Office 2010 together perfectly.  Recently, my daughter switched us over to Office 365.  Since the change, I am unable to open any Microsoft documents through my email unless I save them to my computer first.  I have another computer that uses Windows Live Mail and Office 365 and everything works fine, so I know it is possible to have them work together properly.  What can I do to fix the issue where I can open documents without having to first save it to my computer. Thanks in advance!
