Good morning everybody. I can't modify "to send as" members options in Exchange Administration Center for security groups. This security groups was created in Active Directory. Members are prese...
Proceed by adding members to security groups in Active Directory Server.
I did this.
Old members can send as.
But new members can't. It's not Outlook problem. We select the right email adress in From. They received an error that they don't have permission.

- Try adding a new member address by checking the msExchSendAsAddresses value of the group properties in ADSI Edit!
- 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.- Do you have an on-premise Exchange Server?
If so, set it up in the on-premise management center!
