My Outlook e-mail archive (outlook.pst) fell over when I was adding some files to it. I have run the Microsoft Inbox Repair Tool (scanpst.exe) as suggested. This goes through as far as 100% of Phase 4 of 8 before encountering a fatal error and giving up with no changes made.
The log file runs to 4 pages relating mostly to "bad signature" or "missing required column" a few "row doesn't match sub-object"s thrown in, followed finally by "Fatal Error: 80040900". The machine is a 450MHz P2 running Windows NT 4 and Outlook 97. The Archive file is around 2GB. Any suggestions for advancing the repair?
