This problem occurs because the PR_IPM* EntryID fields in the Inbox do not match the PR_ENTRYID EntryID fields of the folders that are associated with the items. The Import-Mailbox cmdlet copies the PR_IPM* EntryID fields from the .pst file. However, the PR_ENTRYID EntryID fields on the folders are not updated.

To resolve this problem, install Update Rollup 2 for Microsoft Exchange Server 2007 Service Pack 1.
