Why can't I send email from Outlook (microsoft account) to a Yahoo or AT&T email account?

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.

    No need to be condescending and frankly I am not willing to spend hours trying to learn a fix for this particular issue considering my brokerage pays to use Outlook 365. Considering the scope of this problem, I believe this should be addressed by Microsoft. I am a 100% commission based sales professional with limited time to devote to something such as this that is not my area of knowledge. I am also not the administrator for my brokerage so I don't have the ability to take these steps and am forwarding instructions to another person who will have to "figure it out".

    I have the same issue. I don't get any indication that the email did not go through. Definitely started the few few days.

    Since March 8th, there has been an issue sending email to Yahoo and AOL. This is a part of Gmail, Yahoo and AOL implementing new spam policies requiring DMARC records.

    Even though Yahoo states that normal users (not bulk emailers) only require *either* an SPF record *or* DKIM, they're blocking Microsoft from sending without both records. When a Microsoft account is set up, along with the MX record, Microsoft provides an SPF to add to the domain's DNS. That's always been sufficient. It appears to also still be sufficient for Gmail. As of Friday, March 8th, Yahoo now requires both from Microsoft accounts. My guess is that email from Microsoft is considered bulk email and requires both DMARC records.

    It's not hard to set up DKIM. You can follow this :https://learn.microsoft.com...

    Follow the heading, "Use the Defender portal to enable DKIM signing of outbound messages using a custom domain"

    Make sure you have access to your DNS to set up the records.

    Hi everyone. I started this thread because I had problems all of a sudden sending emails to Yahoo email addresses (others related to Yahoo too). I received no responses from Microsoft at all. Only other users experiencing the exact same issue. A couple people mentioned there might be something wrong with our DNS records (SPF, TXT, DKIM, or whatever ... No clue what these are). I finally got an IT for to get involved and they fixed the issue. It was the DNS records needed to be updated/created to be compatible with new email protocols being enforced by some email providers, namely Yahoo so far, but Gmail soon and others after that. The IT did the edits for me as I have no clue, but he got wording from within my Microsoft account online for various DNS records and he pasted them at my Domain providers website (I have GoDaddy but Wix controls these settings g because that is shere my website is hosted). So while I can ot tell anyone exactly what to do, I can tell you there is a solution by updating/editing DNS records with your Domain provider, but I would say to get an IT expert to help with the task. Only took about 30 mins. Unless you are IT savvy enough to do it yourself. I hope this helps! At least I know this all worked for me and I'm emailing back to Yahoo email addresses now.
