Exchange 2013 with Outlook 2013, 1 user that somehow had the default inbox and sent folders renamed to Deleted Items. So I now see three deleted items folders, but one is actually inbox and the other sent items. I logged into webmail, it's listed the same on the server as well, 3 folders named deleted items. No other users having this issue, so issue seems to be isolated to 1 user.
Never saw this before, found many articles on web stating you can't change default folder names, but now I need to change these folders names back to inbox and sent items again.
