Have been using Windows Live mail with Windows 8 & 8.1 for a long time with no problem. All of a sudden it won't send e-mails from my netcarrier accounts but it will receive - no problem. It will send & receive from my Windstream account. I have made no changes to my system other than windows updates when the problem showed up. I have tried with & without SSL and ports 25 & 587 with no success. Don't know why the sudden problem.
