When using Outlook Web app 2010 I am unable to drag my mail from my inbox to folders. When I choose the check mark several emails drag (as if I was holding the shift key) and although they move, they cannot be dragged into a folder. In the past, I was able to choose an email, drag and drop it into a folder.  This only became an issue after I downloaded Microsoft Office Professional Plus 2013.  I have not installed Outlook, but choose to access my email through webmail. Any suggestions?
