Exchange in-store compression RRS feed

  • Question

  • According to Ross Smith IV's article (http://www.exchangeanswers.org/article/dude-wheres-my-single-instance):

    To overcome this bloating effect, we implemented a targeted compression mechanism (using either 7-bit or XPRESS, which is the Microsoft implementation of the LZ77 algorithm) that specifically compresses message headers and bodies that are either text or HTML-based (attachments are not compressed as typically they exist in their most compressed state already).  

    So what is 7-bit compression???

    Thanks for the help!
