Not getting all email

I gave up. I wanted to have all my Cox emails forwarded to my Outlook account as I've done for years, and although Yahoo would theoretically do that, they insisted on deciding which emails were spam and trash vs. going to my Inbox so I had to keep checking Yahoo to fix that as well as my own junk folder in Outlook. I sent several emails to Yahoo, but I kept receiving canned answers explaining how to use the Not Spam feature but not answering my questions. I ended up creating a new Outlook email address yesterday and am slowly notifying all my contacts. So frustrating. So badly handled by Cox.
