We had a pretty good thread a while back about our dumbest mistakes, let's turn the tables and talk about the idiots that we have to put up with. I had a client who not only refused to empty his "deleted items" folder, he had an entire hierarchical organization with tons of folders in his deleted items. I tried to explain to him that if they were that important, he should file them in his inbox folders instead. This was a constant battle as he was always flirting with the Outlook 2GB .pst size limitation. I had to force him to go through and at least delete the "real" deleted items such as spam.
