Are you able to send and receive email to your Cox account on Mac? If so and you haven't seen your email yet some users have reported that Cox must first migrate that email to Yahoo who will in turn migrate it to your account--and it could take several hours or even days if that is the case. Check you Yahoo webmail--if the mail you are looking for is there than your setup on Mac is incorrect. If it doesn't show up in webmail it has not yet been migrated.
I can still send and receive on Cox account using Chome and on my phone. A month or so ago, when I signed in, message popped up to click link to Yahoo to migrate over. I did but nothing happened. I have 3 other accounts that had the same message and the migrated over.
Using Chrome--that means using webmail. Not sure I am the best person to advise you--suggest you contact Yahoo customer service.
Hi, We will be glad to check to see if your account has migrated to Yahoo. Please email us at cox.help@cox.com please include your full street address and a link to this forum thread.
