Exchange 2010 got rid of Single Instance Storage and so unfortunately that 2mb attachment will be stored individually in each user's mailbox (taking 1gb of server storage): http://blogs.technet.com/b/exchange/archive/2010/02/22/3409361.aspx

Most OUTLOOK clients are now 2013, but I don't think that matters. My CIO has asked me to verify some things today regarding storage. I am pretty certain I know the answer to my first question but asking for clarification before I answer to him. DEAN sends an attachment to 500 internal faculty with a 2 MEG attachment. My understanding is the specific attachment will be stored only once on the server (taking 2 MEGs) and not stored individually in each user mailbox ( taking 1 GIG of server storage). Please clarify. Second question from CIO regards users who put a graphic in their footer. I never thought about this question before So DEAN has a 100K graphic in his footer and sends emails to 500 faculty users on a daily. Is that graphic in the footer stored in each users mailbox (taking space) or is it handled like an attachment with only a single point on the server taking 100K storage or does that footer add 100K to each user mailbox each time the DEAN sends and email. Thanks for any response or questions. Dana
