I recently exported my Outlook PST file (Win 7, Office 2007), and am now trying to import it into Outlook on a new computer (Win XP, Office 2010). However after importing it is evident that only a fraction of my emails have been imported. Is there any way to diagnose this problem? Any help would be appreciated.
Here is some relevant info:
--PST Filesize = ~3GB
--On the new computer, I *first* tried importing into Office 2007. When I did so, Outlook informed me that the file needed repair, and ran the Outlook Inbox Repair Tool. After it said that all errors (which numbered in the hundreds) were successfully repaired. But many emails were missing from the import. Then I tried upgrading to Office 2010 but was met with the same result.
