Set-MailboxSentItemsConfiguration isn't delivering mail to the sent folder of the delegated mailbox

All,

I have an Exchange 2010 SP2 UR4 v2 environment and when the following command is applied, mail messages from the delegated person's sent folder, does not get copied into the delegated mailbox's sent folder.

Set-MailboxSentItemsConfiguration –Identity ‘CEO Mailbox’ –SendAsItemsCopiedTo SenderAndFrom –SendOnBehalfOfItemsCopiedTo SenderAndFrom

I thought this was suppose to take care of this.  Now must the Information Store be restarted each time the command is applied to a mailbox?

What gives?

Thanks,

Christian
