Shared Message store in Microsoft exchange 2010 and 2013

First - an example of what a shared message store is.  User  sends an email with a 10 MB attachment to 50 users, a share message store would keep a copy of the attachment. When a users wants access the attachment the application opens the attachment on the shared message store.The attachment would not go to each user -consuming disk space with 49 attachment duplications

Does Microsoft Exchange server 2010 or 2013  have that feature available?  It might not be called shared message store but something else.

thank you
