As others have noted you could have a corrupt item or you are hitting the ExMerge 2GB ANSI PST limitation. if you have just one mailbox that is problematic then performing the export via Outlook is the way to go, just ensure that you export to the
UNICODE PST format since the UNICODE format supports PST files up to 20GB in size.
Now if you have allot of mailboxes in excess of 2GB then you may want to consider a third party tool like Lucid8's DigiScope
http://www.lucid8.com/product/digiscope.asp since it can Open Offline EDB's or Connect to Online Production Exchange Servers so that you can then Browse, Search, Export or Recover Mailboxes, Folders
or Individual eMails, Calendars, Notes and other Messaging Items.
P.S. I would absolutley check your other PST files that you say exported without error to ensure they are under 2GB in size and that you can open them. Reason I say this is becuase I have experienced and spoken to others where
the PST files appear to export properly from ExMerge, however, they are over 2GB in size which emant they were corrupt and there is nothing you can do to fix a ANSI PST that is over the 2GB and therefore you must export it again using the UNICODE format or
Export again with ExMerge and break it up into multiple ANSI PST files but that has allot of challenges as well.
