Hi, I created a mailbox and now want to grant a mail-enabled universal security grp "send on behalf" permission for that group. When ever, I am trying to set the "send on behalf" permission for that mailbox from EMC, the group doesn't show up in the list from the add button. I tried several times but no result. How can I set the "send on behalf" permission for a mail-enabled universal security to a mailbox from EMC (NOT FROM THE OUTLOOK). Any quick reply will be highly appreciated. Rgs, Imrul

Try using the Exchange Management Shell using the following command: Set-Mailbox UserMailbox -GrantSendOnBehalfTo GroupHere MVP | MCSE:M | MCITP: Enterprise Messaging Administrator | MCTS: OCS + Voice Specialization | http://www.shudnow.net

Hi, Thanks for the reply. I tried as suggested but failed. I think its not possible to grant a mail enabled sec universal grp the required "send on behalf" permission to a mailbox. It only allows mail user or user mailbox to have that permission from EMC/EMS. If I have to do it for Distribution Grp, I have to do it from OUTLOOK. This is my finding. Anyother comments/ findings will be appreciated. BR....Imrul

Hi, Yes, it's only available in Outlook. That's by design. You Cannot Set "Send on Behalf Of" Permissions to a Distribution List by Using the Exchange Server Administrator Program http://support.microsoft.com/kb/273459/en-us Thanks Allen
