When you migrate mailboxes from an IMAP4/POP3 server to a server that is running Microsoft Exchange Server 2007 Service Pack 1 (SP1), you generate personal folder (.pst) files for the mailboxes. Then, you try to import the .pst files to the Exchange Server 2007 server by using the Import-Mailbox cmdlet. However, the contents of the .pst files are not imported into the Exchange Server 2007 mailboxes.
This problem occurs because some properties of the folders in the .pst files are missing.
To resolve this problem, install Update Rollup 2 for Exchange Server 2007 Service Pack 1.
