Does anyone out there know, if someone sends an attachment, say a 1MB pdf file to all users on the Exchange 2000 server, does the server store the attachment 'once' and put 'logical pointers' in all users mailboxes to the physical file location, or does it store the file physically in every users' mailbox?
