For years, I have been sending emails from Outlook on my desktop computer and mobile device with no problems. But the last few days, I am getting rejection messages saying my emails cannot make it through. Can I get help figuring out what is going on?
Here is the undeliverable error message I got when trying to send to an att.com email address (came from here: Mail Delivery Subsystem <******@xxxxx.prodigy.net>):
"The original message was received at Tue, 16 Jan 2024 12:28:35 -0800 from mail-mw2nam12on2049.outbound.protection.outlook.com [40.107.244.49] ----- The following addresses had permanent fatal errors ----- (reason: 554 [RL02] Message content not accepted for policy reasons; see https://postmaster.yahooinc.com/error-codes) ----- Transcript of session follows ----- ... while talking to mx-sbc.mail.am0.yahoodns.net.: >>> DATA <<< 554 [RL02] Message content not accepted for policy reasons; see https://postmaster.yahooinc.com/error-codes 554 5.0.0 Service unavailable"
And here is the undeliverable error message I got multiple times when trying to send to a yahoo.com email address (came from: Microsoft Outlook <******@xxxxxxx.com>):
"Delivery has failed to these recipients or groups:
(******@yahoo.com)
Your message couldn't be delivered. Despite repeated attempts to contact the recipient's email system it didn't respond.
Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their email system isn't accepting connection requests from your email system. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.

Thank you for help.

How do we obtain an update on this? It’s impacting my business worldwide as we cannot provide customer service to any customer with a yahoo email address. Really need a fix!
The only thing that we know works for this issue is to set up DKIM records with Microsoft and your domain's DNS. If you look back on this thread, you'll see more detailed explanation. Other than that, I don't think you'll get any answers from either Microsoft or Yahoo.
I setup dkim records in both and still cannot send emails from Microsoft to yahoo, aol, or att domains.
So, you went to this link in your Microsoft portal?: https://security.microsoft.com/authentication?viewid=DKIM
And the domain records you got from turning on DKIM were added to your domain DNS?
Also, you can verify that the DKIM records are working by going to:
https://easydmarc.com/tools/dkim-lookup
And check your domain. Check the checkbox that says "Detect all selectors" The "Selector" prompt will change to "Auto"
Hit the "Check DKIM" button, scroll down and you should see the public keys for "selector 1" and/or "selector 2"
If you don't, your DNS is not set right.
