has anyone any idea why my outlook has started downloading every e-mail I've ever had, despite my having deleted them when I first read them. They are coming back "unread" and I have to st p receiving after today's have come in. The trouble is, it has got back to Oct 2012 and says it has 14,000 to go. How do I stop it? I've told it do clear old messages off the server but to no avail.
