I have created a new distribution list in both Active Directory and also in Exchange Server 2010. The list works correctly and when i send mails to it it gets distributed as it should to the people in the group.
Problem is i can not send e-mails from the group name, I am getting the following bounced back to me every time i try
Delivery has failed to these recipients or groups:
You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.
Now i have gone in to AD and set the security to allow send to for Authenticated Users, As a member of the group i assume i am authenticated??
I have tried to send from one or two other lists after changing the setting above an no problem,
Cant work out where i am going wrong,
Anyone any ideas??
