Copied Outlook pst file (2+ gig) to external disk in Preparation of disposal of computer. Now cannot open the file in Outlook on new computer. Have tried opening, importing, creating new profile (both as 2003 file and as earlier 1999-2002 file) and everything else I can think of. Outlook versions are same - 2003. Since I have already disposed of the other computer, I REALLY need access to my old e-mail and contacts. Same result with every effort - Not a pst file - notwithstanding it has a pst extension.
