The information store may stop responding after the message transfer agent starts in Exchange Server 5.5

When you start a computer that is running Microsoft Exchange Server 5.5, the information store may stop responding after the message transfer agent (MTA) starts.

This problem occurs after you move a user's mailbox from one Exchange Server 5.5 computer to another. In this scenario, some e-mail messages may remain in the InTransitFolder folder after you move the mailbox.

Messages are delivered to the InTransitFolder folder when you move a user's mailbox to another server. When the move is completed, the messages are delivered to the new destination server. However, if some of the messages in the InTransitFolder folder have more than one recipient; the Exchange 5.5 information store may stop responding when the MTA tries to deliver them.
