My Cox-->Yahoo-->Outlook journey
I see lots of posted problems with this email transition problem and I wrestled with it for a couple days.
I had no problem setting moving Cox-->Yahoo and getting email on the Yahoo website but I wanted to use my desktop Outlook program as I always have. Trying to just change the incoming and outgoing servers in Outlook wasn't working - just gave an unhelpful failure response. Maybe this could work easily if you use the "trick" I mention below.
This morning I called Cox support, was on hold for ~15min before reaching a quite helpful woman who almost succeeded. Key things from her: in Outlook:
- File-->account settings-->account settings-->remove existing account (this will "re-populate" from your working Yahoo account when your done),
- account settings-->new enter your email address (the one you just deleted) and a password. She said to use the Yahoo email PW which doesn't seem to make sense since you haven't pointed to the Yahoo server yet. But after the next error message you get to enter the server information (as widely disseminated this is imap.mail.yahoo.com and smtp.mail.yahoo.com). We tried this many times (including reboots) but it never worked. Always got the error message.
She kicked me "up" to a guy who knew less but told me to go to Yahoo support and gave me a phone #.
Yahoo answered immediately, went into remote control of my computer and did the same steps but with one difference: they used a password generated for my Outlook by Yahoo. (This is commonly discussed in support forums and I'd already made one but hadn't used it here.) Anyway he deleted mine, made a new one, and used that PW when connecting to imap.mail.yahoo.com and smtp.mail.yahoo.com. That worked, that was the difference. If my first Cox support person had realized this we'd have saved a couple hours.
