Sharp AR M237 Scan to folder

Hi and Marry Xmas to all. I have a sharp ar m237 and it was working fine Scanning to Email and all of a sudden it stopped. I tried everything i could think of, check incoming and outgoing and pass word, all good. Not great on sharp, but i know mita and ricoh, Not sure what could have happened. their using Att for mail and I called them, he said log in to their account and go to Yahoo and log in, which is odd to begin with. So im thinking just scan to folder, can anyone help.
Thanks.
Bill
