Thx for response. But I think my problem still not solve yet. Currently I am thinking : 1. Create many pst (how about my computer memory?).Even till now, already 8 time illegal operation, since change. 2. Waiting office 2003 (I don't think come next 3 months & office stability itself?) 3. Backup pst? I need to monitor my pst every day?
