Can a Microsoft Exchange expert recommend software to use to merge several exported mailboxes to PSTs. For example; a user has a mailbox exported to a PST from a 6/2008 RSG restore and a PST from a 10/2008 RSG restore and a PST from a &nbsp;4/2009 RSG, how can I merge the 3 PSTs into one PST and rid of any duplication. I am looking for a software utility I can buy that performs well and easy?
