Hi all, I'm looking for sending mails as a Dynamic Distribution Group. But in EMC or AD console, I don't find this rignt. Here the rignts I see : Full control (Although checked, not sufficient) Read Write Read Exchange Information Write Exchange Information Read Exchange Personal Information Write Exchange Personal Information Special Permission Of course, every time I changed rignts attribution, I rebooted the "Exchange - Information Store" service. Anyone know how to do it? Thanks. Have a good week all.FXE
