problem synchronizing P800 contacts with Outlook 2000

Hi everyone,

I have synchronized my P800 contacts with Outlook 2000 on Windows 2000
pro thgrough the cradle in USB.
My problem is that I have 2800 contacts and a lot of them are not sent
to the P800 while synchronizing. I have tried many times to
synchronize, the software says synchro complete but I still have the
same problems: a lot of my contacts are missing in the P800.

Does anyone have an idea ?

thanks,

Kais
