Ok.
The msExchSendAsAddresses value was empty. So it can't be the right options because I have some old users that can send as this security group.
But I did what you said. I'v added one member in msExchSendAsAddresses. I'd waiting M365 synchronisation. I'v tested send email. But error again. I'v found another how-to in Internet (https://tchekbo.wordpress.com/2021/08/09/send-as-or-send-on-behalf-for-active-directory-distribution-group-office-365/) so I add this member in security and allow "total control". I'd wait another synchronisation. Test again. Error again.

- TAE_YOUN_ANNJul 21, 2023MVPDo you have an on-premise Exchange Server?
If so, set it up in the on-premise management center!- Frdrick_LefebvreJul 24, 2023Copper ContributorNo. There is only cloud (via Microsoft 365) Exchange Server.
