we have Exchange 2003 and Exchange 2010 on the network. almost all user mailboxes are in Exchange 2010. emailxtender mailbox is still on Exchange 2003. i want to export users mailbox archives by user mailbox. i tried to use exSearch and select a mailbox and nothing shows up. if i use the user's name in search for words, i see the archive emails. however some e-mails that do not belong to the user shows up because the user's name is mentioned in the email or in an attachment. is there a way for me to export the pst by user mailbox?  thanks.
