Cannot send emails to AOL or Yahoo

Hi, for months I have not been able to send email to either AOL or Yahoo email address. Every other one works. Is there a fix for this? Thanks Liam Hayward

When Office 365 tried to send your message, the receiving email server outside Office 365 reported an error.

How to Fix It

Check the "Reported Error" from the "Error Details" section shown below for more information about the problem. The error might tell you what went wrong and how to fix it. For example, if the error states that the message was blocked due to a potential virus or because the message was too large, try sending the message again without attachments.

If you're not able to fix the problem, it's likely that only the recipient's email admin can fix it. Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin about the problem. Give them the "Reported Error" from the "Error Details" section below.

Did you get resolution? If so, how did you resolve? I am having the same issue! It only started when I upgraded to Windows 11.

Thanks

  Roamphotos I’m having the same issue with aol and yahoo addresses. Occasional bounce backs go into junk a few days later. I’ve checked and my domain isn’t on any spam lists.
