Hi All, Ok so in Exchange 2007 you could mail-enable a securtiy distribution group and then crack open a shared mailbox and delegate the distribution group to be able to send on behalf of that shared mailbox. Now that we are in Exchange 2010 this no longer works?? I tried doing the same process with no such luck. I have also used the following powershell command. get-mailbox -identity "name of mailbox" | set-mailbox -grantsendonbehalfto "distribution group" the powershell works as I see it in the get-mailbox | fl however it does not show in the gui the group nor do the users have the ability to send on behalf that are in the distribution groups. Please help out.. What am I missing... Thanks in advance!!

Is it a mail-enabled universal security group?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi Robert, The GrantSendOnBehalfTo parameter specifies the DN of other mailboxes that can send messages on behalf of this mailbox. You can get more information in this document: Set-Mailbox http://technet.microsoft.com/en-us/library/bb123981.aspx When you try to grant a mailbox send on behalf of permission to a group users, you can achieve the goal by this way: 1. Make sure you group is a mail-enabled universal security group. Mail-Enable or Mail-Disable a Security Group http://technet.microsoft.com/en-us/library/bb123805(EXCHG.140).aspx 2. Use this command to grant send on behalf of permission to a group users: Note: In my test (“help desk” is a shared mailbox, “gg” is a mail-enabled universal security grop) [PS] C:\Documents and Settings\Administrator>$Users= Get-DistributionGroupMember "gg" | foreach {$_.name} [PS] C:\Documents and Settings\Administrator>set-mailbox "helpdesk" -GrantSendOnBehalfTo $Users After you run these commands, users in group (gg) have shared mailbox(help desk)’s send on behalf of permission. You can run this command to check: Get-mailbox “help desk” |fl Grant* Thanks Evan Liu TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.
