Outlook 2003 shouldn't have any trouble with very large PSTs unless they're
still in the old ANSI format. You can have Outlook tell you with
right-clickPropertiesAdvanced

and I use VP Professional, and
interesting enough I have the same problem on my office and I use
windows 2000 server, same outlook.

XP Professional, I suspect you meant.

I also use plaxo and that could be the common problem. and I can't
use the shift key to delete single or multiple contacts.

Plaxo is known to cause significant side-effects with Outlook. Were I
having the problem I'd disable or uninstall Plaxo. When you say "can't",
what stops you? Select the items you want to delete, hold down shift, and
press Delete.
