Setting up my cox email account on my iPhone 5s, it gives me an error during the autoconfig that the password for imap.cox.net is incorrect.
I can sign into my webmail account just fine on any computer. I've even changed my email password a couple times but no matter what I do I can not setup my cox webmail because I can't get past this error.
I'm following the online directions:
Settings > Mail, Contacts, Calendars > Add Account > Other > Add Mail Account > Name,Email,Password,Description...Next > ERROR "Cannot Get Mail - The user name or password for imap.cox.net is incorrect".
Do you have anything else, like Thunderbird on a laptop, to test with?
Also, try with just the username for email, and not the full @cox.net part.
Last, try via the manual method as documented here. Sometimes the autoconfig gets glitchy.
