OK, guess I should give more info, using Win7, IE11, Xfinity connect, but using Windows live mail for reading and sending. In one particular case I send a group is 97 emails as a news letter and one email bounces that I have sent to for several years with no problem, I just yesterday sent another group email and it didn't bounce, tried to sent the news letter after the last one went through but it bounced again.......Very strange that one out of 97 won't go through.....
