Exchange 2010 Delegated Sent Items

There has been a major change with Exchange Server 2010 SP2 RU4 with reference to Delegate Sent Items.

Scenario
The user “Delegate” has been assigned Full Mailbox Access and Send As permissions to the user “Manager” mailbox. This is accomplished using the below powershell cmdlets.

Add-ADPermission -identity Manager -User Delegate -ExtendedRights "Send As”
Add-MailboxPermission Manager -User Delegate -AccessRights FullAccess -InheritanceType all

With Exchange Server 2010 SP2 RU3 and lower, whenever Delegate would use Send As permissions and send an e-mail to any user, the item would show up in the Sent Items Folder of Delegate. With Exchange Server 2010 SP2 RU4, this behaviour changes; you can now make a copy of the e-mail in the Sent Items folder of the Manager Mailbox. To achieve this functionality we are introducing 2 new powershell cmdlets;

Get-MailboxSentItemsConfiguration
Set-MailboxSentItemsConfiguration
