Mail won't open Yahoo
I have several email accounts. However my .btinternet now refuses to display my mail. I have been to accounts, put in my password, right clicked the little icon and clicked take yahoo on line. All to no avail. I can open it via browsers no problem. I know that my password is good. I have tried taking it off mail and then putting it back on. Is there anything else I can try - anyone know what's going on?
