We run Outlook 2003 on an Exchange Server.  We give our users a limited
mailbox size to reduce space on the server.  
One of our users Calendar has 33MB of data stored in it.  I know that I can
run auto archive to get rid of the old data, however what I don't know is how
to stop the Calendar from storing attachments sent in Calendar invitations.  
Is there anyway of just saving the invitation but not the attachment?

Thank you,
David.
