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.

    Our organization was having this same issue with Yahoo and AOL accounts. We use Outlook for our company email. I was getting frustrated with the issue so I looped my broker (head of our organization) into this situation as I don't have admin rights. He finally messaged Microsoft customer support today (4/9/24) to set up a call and the support person had him go through the steps to correct the issue. It took him 30 minutes for all of it and he said they were super nice and helpful! I tested it and the problem is resolved for Yahoo and AOL email addresses coming from my business Outlook email.

    I guess that is what you will have to do to resolve it unless you want to spend a ton of time reading through the instructions on various pages. Good luck!

    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".
