Using an iphone 6 (but replicated issue on iphone 7 and ipad) when not on Cox wifi, I am not able to send emails from the Cox email account. All outgoing server settings are correct. I can access on my Mac and via web mail. Error message comes up that says 'Cannot Send Mail The user name or password for 'Cox' is incorrect." It works every where else so that is not the issue. Account has been deleted and added, phone rebooted, and various other approaches tried. I see other forums indicate this remains an unresolved issue. For me, it started appearing about two months ago.
Having spent over three hours with Cox technical support last week to be told it is a Verizon issue, I am looking for an answer. Verizon told me, after 70 minutes of tests, it is definitely a Cox issue. Given I can access from my Mac and the same error message appears when I set up the account on an iphone 7 and on the ipad, I tend to agree.
Looking for some answers and quick solutions.
My wife's iPhone is experiencing same issue. Could you indulge this elderly guy by listing explicit directions to delete cox, turn off phone and especially the "cox email address
I have been having the exact same issue and have tried everything to resolve, including this. Any other options to resolve?
