In Outlook 2013 the search hangs on "searching" and no results are displayed. It does this for all 4 email accounts connected to Outlook (all IMAP). It used to work. I tried rebuilding the index and it worked again but only one time. I tried rebuilding the index again and it didn't fix it again. I tried trouble shooting and it said it couldn't find anything wrong. Any suggestions? I'm running Windows 8 64bit.
