I understand that when zimbra receives an email to one user and copied to 9 other users in the office, only one copy of the email is stored with appropriate links.

We have several accounts that are each used as a repository of emails to be shared on a project basis. If all 10 of the recipients move the received email into a shared folder on a different account, will there still be a single copy saved? If some copies of the email go into one subfolder of the shared project folder and other copies go into a different subfolder of that project folder, what effect will that have on the number of copies that zimbra maintains?

Also, how does this affect the number of copies of any attachments involved?

This may sound silly, but getting people to look for duplicates before moving emails happens about 10% of the time!
