Hi, Do you get any error message when you send to the moderator?Adam Bokiniec

I would check the following 1. Ensure the group is setup correctly for moderation, i.e is set to ModerationEnabled, ModeratedBy is set or ManagedBy parameter of the distribution group. 2. You're ArbitrationMailbox exists. 3. Use Get-distribution group to get the info for point 1. http://technet.microsoft.com/en-us/library/bb124755.aspx Sukh

Hi Jason, Moderator Mailbox is vaild, and i can find the message in queue. RegardsSami Hammad

Hi, So the Approval request message actually send to the Moderator. However, it stuck in queue which cause the Moderator cannot receive Approval request email. If in this condition, check the message in the queue view.The Queues view displays valuable troubleshooting information, such as the Last Error and the Next Retry Time associated with each queue. Try to find why the message is stuck in the queue.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.
