Starting this week, our emails to yahoo and aol accounts are not being delivered, but emails to other email accounts are working. Here is one of the yahoo error message: 1/12/2024 9:27:16 PM - Server at SJ2PR02MB10076.namprd02.prod.outlook.com returned '550 5.4.300 Message expired -> 421 4.4.2 Connection dropped due to SocketError' 1/12/2024 9:26:15 PM - Server at mta5.am0.yahoodns.net (67.195.204.73) returned '421 4.4.2 Connection dropped due to SocketError'

I believe the reply I just posted on the next page also answers your question, but let me know if it doesn't
a custom domain email is not linked to hotmail. You can buy a business plan and link custom domains in o365 or outlook.com. In cases of free email providers, you will need to look up how to configure dmarc and dkim settings on that providers email. They will handle the spf automatically. Not all free email services offer this. You can verify your records by using tools at mx****
That was the answer I was afraid of. Sigh. Microsoft, please fix your stuff. Thank you for your fast replies, I will use another email for now.

There is nothing you can do to fix it. It isn't your responsibility. Microsoft should fix the problem All you can do is wait or use other mail provider until your hotmail.fr issue gets resolved.
No, just trying to send normal emails to my sister who uses a yahoo.fr email, and she's not getting any of them. I'm on hotmail.fr too, if that matters at all. (maybe .com is different... I don't know)
