As posted many times on this forum, you must not Import pst files because
importing can corrupt them. Copy the pst to your hard drive without
overwriting any outlook files. Then use File, Open OL Data File to open and
use it.

I installed Vista Ultimate and am running Office 2007 Enterprise. All
updates done. I imported my old .pst file from my previous XP Pro
installation (copied it to the new hard drive). Since the import I cannot
get Outlook to react to the cursor and have to close it down via Task
Manager.

Any help appreciated.
