With no obvious cause the Contacts folder on my Mum's computer appears to
have become corrupt. All other Outlook folders are fine. She is unable to use
addresses for new email messages, some data is missing, the Contacts cannot
be exported, syncing with a PDA does not work. We have tried scanpst (does
not complete) and scndsk with no success. From what I can see in this forum
the only solution may be to create a new pst file and export all other intact
Outlook data to it. Then use this file to replace the current one (I assume
by simply dragging it into the appropriate folder) and then syncing with the
pda to restore the missing entries.

Any thoughts on this or advice would be welcome. Thanks.
