JE NARRIVE PAS A ENVOYER NI A RECEVOIR DES MAILS

Hello Jean,

I would like to start with an apology as I feel you may have been sent to this website in error. Tech Community is not a support site and doesn't have the resources to respond to support questions.

Regarding the email situation you are experiencing, I am not aware of any server issues. There were some changes to storage allocations and email recently that you can read about here: Modifications apportées aux fonctionnalités de messagerie microsoft 365 et au stockage - Support Microsoft

If you feel it may be something other than that impacting you, then I suggest creating a question at this link to get some support: Résultats dans Outlook - Communauté Microsoft

Also, final note for your safety, I edited your message to remove the phone number you provided. Posting that in a public forum puts you at risk and is never a good idea. If Microsoft ever needs it, we will ask in a secure manner.
