I have had the same problem for the past month. I do not use outlook. My email client is Thunderbird and I get the same 'enter password' message usually around noon for a few hours. Then it goes away without doing anything different. Problems must be with Cox as many people seem to have the same problem.
This has been happening to me intermittently. And it is REALLY ANNOYING. I changed my password over a month ago, so I don’t know why it still happens. But when it does, it is as if all of the Outlook spam filter rules I have set up stop working for the LOVELY DAILY SPAM THAT COX REFUSES TO DO ANYTHING TO FILTER OUT OF OUR INBOXES. It’s as if it’s backdoor sabotage to get around the filters we set up in Outlook to filter out the junk by kicking us off of Cox’s server and letting it get into our inboxes that way.
Mark it down: at 7:00 ET Wed 5/20 I was ONCE AGAIN prompted by Outlook to enter my username and password for imap.cox.net. WHY AGAIN?!? AND ONCE AGAIN FOR THE NEXT WEEK, OUTLOOK SOAM FILTERS WILL BE USELESS IN BLOCKING THE 6-10 WONDERFUL SPAM EMAILS THAT I GET EVERY MORNING THANKS TO COX DOING NOTHING TO BLOCK SPAM. NOW I’M BEING KICKED OFF THE IMAP SERVER DO I CAN’T USE OUTLOOK FILTERS TO BLOCK THEM. IT’S ABSOLUTELY HOPELESS!!’
Hi JP Sports. It is possible that your password in Outlook may be corrupted. You may want to verify that the incoming user-id doesn't have @cox.net in the name and remove the password and save it. You will get an error but it will log this change. Then input your password and save it. - Lisa, Cox Support Forums Moderator
