Outlook 2003 locks up

[devastator]

Seems to lock on all workstation when trying to type a new email, click the To: button, and change the default list from Global to their Personal Contacts. Says "Outlook critical error" then locks up and you have to CTRL ALT DEL to close. The first message was something about contacting Microsoft for a client application or something. All these workstations have office 2003 sp1 and XP Pro SP2. The problem existed before SP2 but I don't think we had the issue until after installation of SP1 for Office.


Any ideas?

The exact errors are as follows.

The address list could not be displayed. The operation could not be completed because one or more parameters are incorrect. Contact Microsoft Technical Support for the client application.

Unable to complete the operation. A fatal error has occurred in Outlook.
