I'm not sure what you need but this is the information from "About Outlook".
Outlook 2000 SP-3 (9.0.0.6627). Internet Mail Only - Security Update.

I've recently reinstalled Office from the original CD following a Windows
reinstall. The only thing that may be different from my original
installation is that I was directed to a MS Office site to dowload updates
etc. I don't recall doing that previously. I think that's where the SP3
comes from.

Does that help?

It doesn't just happen all by itself for no reason.

I am using Outlook 2000 and Win XP Pro SP2 and have done for years. For no
apparent reason I can no longer add contacts to the Outlook contact list.
The "New Contact" entry form comes up as normal, I enter the details as
normal, I click either Add or OK or both and the screen disappears. But
the
new contact isn't there in the list. I've repaired Office 2000 from the
CD
but the problem persists.

Anyone any ideas please?
