    I continue to have the problem that I am unable to send email from my Microsoft Outlook account to yahoo or AOL accounts… I can receive from them, but not send it to them…

    What is the solution?

    Are you using your own custom domain, or is it an outlook.com email? The solutions have been posted, you just need to read the thread. Page 3 is where we start giving the answers, and page 6-7 has several solutions summarized. The solution is unique for each domain that is having the issue.

    We were able to resolve this by adjusting the security settings. I'm not an IT expert, but it involves the DNS record and the DMARC email security protocol. Someone else provided a good explanation above.

    Could you mention who posted the information to resolve this, please?
