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)
Does your issue have something to do with mailing list?
Sorry if this is the wrong thread. The issue is that I cannot send emails to yahoo addresses so I thought this is the same issue.

Remote server returned '550 5.4.300 Message expired -> 451 This mail has been deferred because the sender is sending too much mail for its authentication status. Please set up DKIM aligned to the From: domain. See https://senders.yahooinc.com/smtp-error-codes#authentication-failures for more information.'
I checked the Yahoo link, but I don't really know what DKIM is, and I'm not sure I have access to it under just hotmail.
