    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?

    Start on page 1 and read the thread. Most of the answers that resolved the issues came from Ron, and a few from myself.

    I just began having issues sending emails from my Microsoft Office 365 Outlook emails to persons with YAHOO and AOL email accounts. What is the status update on a resolution, or is a fix still in progress? - Thanks.

    If you post your domain name (NOT the ENTIRE email address), I can lookup your DNS records to see if something is incorrect. That's ok if you aren't comfortable posting your domain name. If that's the case, contact GoDaddy and ask them for help.
