We need to create a main contacts file that can be stored on our SBS 2003
and
shared by all users. Some users operate Outlook 2000 and some Outlook
2002.
The Contacts can be mapped to the same file, but the file cannot be opened
by
more than one user at the same time. Is there another way to achieve
this?

Thank you
