Exchange 2010 - Problem Printing Calendar in OWA

If a user doesn't have Full Permissions on a Exchange 2010 mailbox, the user can't print the OWA calendar.

When I select the printer object, the error on the IE page is "The item you tried to access no longer exists.  The item wasn't found.  You or a  delegate might have moved or deleted it using another computer or mobile phone."

Loading...  just keeps running.

Any suggestions?

Thanks
