Does sending an all staff with an attachment take additional resources per recipient? RRS feed

  • Question

  • We had a user send a picture that was mostly unrelated to business, not a huge deal at this company, but we questioned if sending one picture to several recipients duplicated that image size throughout everyone's mailbox. Is this true? Does the server create a copy for everyone and does that multiply the amount of space taken on the server?

    Each recipient has their mailbox size increased by the size of the
    message.

    That's a different question.
     
    Exchange 2010: No
     
    Exchange 2007 and earlier with a single database: Yes
     
    Exchange 2007 and earlier with a multiple databases: Each database
    receives a copy of the attachment if there's a recipient in the
    database.
     
    >and does that multiply the amount of space taken on the server?
     
    Single Instance Storage reduces the space necessary to store the
    attachment. If you're running Exchange 2010 there's no SIS.

    Exchange 2010: Yes, server will create a copy for everyone.

    Just as Rich said Exchange 2010 there is no SIS. You can know more information from this document:
