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.

    Has anyone got a solution from microsoft? I have not and keep having the problem. This has to get resolved as there are too many people having the problem and on our emails to major email providers.

    By the way, I've got rejection now to a couple school districts near me that I've sent casual emails to. They're automated response says that I'm being flagged as spam. So it does confirm what others have been hearing that there's something about the settings for our emails being sent out. That they get flagged as spam. But nothing has been done different by us users. So the resolution has to come Microsoft or from entities we're having trouble sending to. By the way I did go to my domain provider and ask them to change the DNS settings as noted by others and they said that was successfully done. But it hasn't helped.

    Where is the help for this?

    We have been encountering this same issue for months.

    Our accounts receivables is going crazy with clients not receiving our emailed invoices. We had isolated it to yahoo and rogers hosted accounts.

    I am relieved to find that I am not alone.

    I have a client using Office 365 whom is experiencing the same issue sending to Yahoo accounts. This has only started recently, I have checked the DNS records and nothing has changed. Please could supply an update on this issue, is there a DNS change we can make?
