Problème pour le fonctionnement adresses mail exchange sur outlook

Dolores Larroque 0 Reputation points

Nous avons fait évoluer nos adresses de messagerie sur OVH sous exchange et depuis, les adresses ne fonctionnent plus (pas de réception et d'émission). Comment pouvons-nous régler la situation au plus vite ?

    Hi @Dolores Larroque

    Kindly note that currently Microsoft Q&A forum only supports posting in English.

    For us to better understand your question, please consider editing your question into English.

    Thanks for your understanding.

    According to machine translation, your question is:

    Subject: Exchange mail address problem on outlook

    Body: We've upgraded our OVH email addresses to exchange and since then the addresses no longer work (no reception and no transmission). How can we resolve this situation as quickly as possible?

    If there is any misunderstanding, please feel free to point out.

    If the issue is Outlook cannot connect to Exchange server, please make sure you have created an A record or CNAME record in public DNS or your internal network to point to the ip address or server name of the Exchange server.

    If you are using Exchange Online (Microsoft 365), please refer to this link:
