I'm trying to import a 730MB PST file into Outlook 2007.  It was created from a 2007 install on another PC.  I'm importing the entire mailbox into a separate PST within my own session.  When I import the file, I get about 7MB of data showing up.  The file itself is then overwritten and becomes 7MB.  Lucky I have it backed up but does this sound like a corrupt file? There should be several years worth of data in the mailbox but all I'm seeing is the Inbox with no data in it, some contacts, some drafts...no sent items or anything.  When I created the PST I exported the entire mailbox.....strange.

any suggestions?
