That's not the issue she's reporting. She specifically said she can't receive verification codes from Microsoft at her Cox email address. I'm having the same issue and just made a forum posting a few minutes ago.
For example: When setting up a Microsoft Outlook email account, it'll ask for a different email address to use to verify you're the owner of the Outlook account, if you should ever lose your password or have security issues. She & I are trying to use our Cox email addresses as the recovery account Microsoft can send those emails to. But those emails aren't being received by our Cox accounts. Cox is blocking those emails from Microsoft and/or Office for some reason.
This needs to be resolved by Cox so that they stop blocking legitimate & important security emails from MS, Office, and Outlook.
