The PR_IN_TRANSIT flag is set on the source mailbox to tell the store not to send any new email or make other changes whilst the mailbox is being moved. Same happens to the target mailbox. When the move has been completed, these flags are removed and queued mail is delivered. ----- Original Message ----- From: John Knijn To: exchangelist@xxxxxxxxxxxxx Sent: Thursday, May 10, 2007 8:15 AM Subject: [ExchangeList] Exchange 2003: moving mailboxes Good morning, During Moving Mailboxes from one mailbox-store to another mailbox-store, what happens with mail sent to that particular mailbox?
