Outlook 2003 and Exchange 5.5

I have an Exchange server 5.5 with a public calendar that
users could print using the Daily style when using Outlook 2002
or earlier. When I have upgraded users to Outlook 2003,
they can access the public folder and see the data, but
cannot print using the Daily style they must use the Weekly style.
Even if I add the user with Owner
permission, they cannot print using the Daily style. Only users that were
listed in permissions before the upgrade to Outlook 2003
can print using the Daily style. Please advise. Thanks.
