We have recently moved to Exchange Server 2010 and while testing the features of OWA 2010, I am trying to use drag and drop for attachments or the ctrl-c, ctrl-v to paste attachment to new message. Neither of these seem to work. Nothing happens or I may just get a hyperlink to the physical location of the file on my drive. The old way of attaching files works fine. I can click the paperclip and browse to the file and tell it to attach. I would like however to get the drag and drop feature working. I have tried this on multiple computers in and out of our network and on IE8 and Firefox with no success. Any help on this is much appreciated.
