Update :
Choosing the option “Accounts in any organizational directory (Any Azure AD directory – Multitenant)” in >Authentication in Azure’s option, solved this previous issue.
But now, there is the error “The mailbox is either inactive, soft-deleted, or is hosted on-premise.” :/
This is a shared mailbox.
Can it work ?
This type of issue comes if you are using an admin account that does not have a mailbox. Other than that, the error also comes if your account does not have an Exchange Online mailbox.
If you have a valid Exchange Online Mailbox and your account is not an admin account then you can contact Microsoft regarding this as the error comes from their end.

Hi Ibrahim,
Thanks a lot for your feedback !
Indeed, I was logged with my admin account that doesn’t have the User mailbox.
With the User mailbox account it works !
Thinking about security, it is recommended to use the Outlook/Office365 Authentication of the main account (with the User mailbox), on several websites using shared mailboxes for each website ?
This is only to get WordPress emails (contact form and technical/maintenance emails), not for mass marketing campaigns.
Hello Maxmle,
You are welcome!
If you do not send bulk emails or have too low a volume to send from your website you may use the shared email account.
I would recommend using AWS SES type delivery provider for Transactional Emails for your website which also supports multiple authentications for multiple websites for the same email or domain.
