Sounds like your users have profiles that include a .pst file as the default
delivery location. Instead, they should be using the Exchange mailbox as the
delivery location.
How were they sharing their calendars earlier?

in outlook 2000 they could share it with anyone with an email address
it would send the updates via email.
but it wont work like that anymore with outlook 2003.

You are apparently referring to the Net Folders feature, which died a
deserved death with Outlook 2002.

Never and still havent had a problem with net folders and not about to
change our mail server just to share address books and calenders. It
is the reason why we will be staying with Office 2000 and not
upgrading
