After entering a few dozen contacts into Outlook Contacts
(Office 2000 Pro, with SP-3), all of a sudden I started
getting the error message, "The messaging interface has
returned and unknown error. If problem persists, restart
Outlook." I restarted Outlook, reinstalled MS Office and
installed the service pack 3 (recommended fix), but still
get the error message when trying to add new contacts.
Any idea what to do now? Thanks.

In order to install Office 2000 Service Pack 3, Office 2000
Service Release 1a must be installed first. The article below
