Outlook problems after moving PST files to new computer

[RuaBozo]

Hello all, I read some similar problems but did not find a solution.
I moved PST files from Outlook 2000 to Outlook XP from a Windows 2000
machine to an XP machine.
85 percent works fine except for the;
1. The Find box in Contacts does not work.
2. I get duplicate emails from particular individuals.
3. Some of the I use for sorting email have gone mad.

Any help to get me started would be appreciated.
Thanks in advance.
Nick
