And here is the aol error message: 1/12/2024 9:27:38 PM - Server at PH0PR02MB7367.namprd02.prod.outlook.com returned '550 5.4.300 Message expired -> 421 4.4.2 Connection dropped due to SocketError'

    here is another crazy thing that is happening. In my Microsoft distribution list, we have email addresses from AOL, Verizon, Hotmail, outlook and Gmail.

    the person from AOL emails the distribution list and it was delivered to everyone. when I do it from Hotmail, AOL Verizon and yahoo don't get delivered and Gmail gets held up for about 30 min to 1 hr. but does get delivered. when the person from an outlook.com address sends to the list comcast emails don't get delivered but everything else works?

    this is nuts.

    please help if you can. should I be calling GoDaddy or Microsoft.

    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.

    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.

    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?
