I've created a distribution group and added a particular user as a recipient of this group. The user would also like to respond as the email of this group.
What I did was open up ADU&C, switched to Advanced Mode, selected the group, added the user and gave them Send-As rights.
It didn't work - every time he tries to send as that user the message bounces back saying he doesn't have permission to send to this recipient:
You do not have permission to send to this recipient. For assistance, contact your system administrator.
I changed the permissions to Full Permissions as a test and it still didn't work, stating the same reason above.
Does anyone have any thoughts on what I've done wrong or missed here?
Many thanks in advance,
