Hello,
this problem occurs for no rational explanation!!
Solution (in my case which should be quite general): in Outlook 2007 - go to Tools then Account Settings, select the account, go to More Settings, Outgoing Server tab, check My Outgoing Server requires authentication, check: Use same settings as my incoming mail server., then confirm and exit.
This has resolved the issue on my different accounts. (I'm using Orange)
Good luck!!

citation http://assistance.wanadoo.fr/reponse27.asp
This problem only occurs when sending messages with Microsoft Outlook Express. It indicates that the address of one of the message's recipients is incorrect.
It is necessary to:
- check and rewrite the addresses of the various recipients of the message;
- delete the message from the "Outbox" of Microsoft Outlook Express and then rewrite the message.

check therefore if you sent it to the correct address and if your credentials are entered correctly.

Bah pour moi, c'est impossible d'envoyer un mail à ma mère sur son travail, ça me renvoie Remote MTA siginternet2.ville-lehavre.fr : diagnostic SMTP : 550. Je ne sais pas pourquoi ça fait ça, c'est peut-être parce qu'ils ont interdit l'envoi d'emails venant de l'externe à son boulot.

Hello everyone, here is the error message that appears on Outlook. I can no longer send emails from here; I have to go on orange.fr, which is less convenient. How can I solve my problem to reuse Outlook?
THANK YOU

ipconfig · Answer

You need to go into the account settings, then on the server "server requires authentication" click on settings and select to log in using: enter the username and password of the current operator.
The incoming server stays the same but the outgoing server in case of an error must be:
mail."current operator"."country"
smtpauth.current operator."country" >>> not forgetting to check that my server requires authentication.
Good luck!
