have a desktop running Windows 2000 sp4, with Office 2000 sp 3. When
the user goes to open Outlook (Meeting Place) they receive the
following error:

Meeting Place for Outlook (Cisco)
"Your version of Outlook is less than 8.5.5630.0. Please upgrade it
before installing this software".

8.5.5630.0 = Outlook 98 (this is a very strange problem)

I uninstalled and reinstalled Office 2000 last week, and it ran okay
until today. Also I have updates Meeting Place to the latest version
for the client.

Once you receive the error, you click ok and continue to use Outlook.
If you try though to schedule a meeting Outlooks shuts down. I tried
logging in on my account, same problem.

I also ran virus and spyware scans, they came back clean.
