The error occurs when making a new e-mail, open the contactsfolder by clicking
the "To" button. The first half of the contactslist is showing, but when I
try to scroll down, or typing the firsts letter of a name at the button of
the list, outlook generates an error message ("Outlook has generated errors
and will be closed down"). And that's is excactly happens: outlook closes
down.

There's  no problem scrolling the contacts from the contactsfolder (so not
when you're making a new e-mail).
There's no problem when the mailbox is accessed on a different computer.
There's no problem before installing office sp3.

Using:
MS Exchange Server 2000
Windows 2000 fully updated
Ms Office 2000 fully uupdated.

Does any know how to solve this problem, other then not installing SP3?
