I have been having this same problem for several months now as well. Same runaround with Cox support. I think they're trying to make it a bad enough experience to force everyone to change to something else so they can just let it die. If someone figures this out, please post something. Definitely a Cox problem, not an Outlook (or Gmail) problem. I've been playing into their game by changing most of my logins to a new email address, but it's frustrating because I've used my Cox email address for over 10 years. Ugh.
The worst thing about this is that once this happens, it is as if Outlook forgets all of my filter rules that I have set up to reroute all of the spam email that Cox REFUSES TO FILTER ON THEIR END into the trash bin. The rules will be there, I’ll run them on existing items in the inbox, but they don’t work unless I create a duplicate of the same rule. I’ve had to create 6, 7, even 10 of the same rule and it is VERY FRUSTRATING. All because I have to re-confirm my password every few days.
