Next I could not send mail with my outlook 2016. I tried my cox webmail and had no issues getting or sending mail. Tech support confirmed all my settings were correct and advised me to use webmail until they fixed the smtp server. Today I exported my mail to a pst file and removed the account. Changed my password for my cox account and added my cox mail account back to outlook -- reviewed the settings and they were the same as before, so I imported my mail pst file and restored all my saved mail. Now I can send and receive mail. we will see for how long. I hope I do not have to go thru all this again ch 137 nfl network preseason game is this channel showing the game all I'm seeing is past games
