The customer with whom I am working at present has a SIS of 6 to 7 on each of four primary mailbox servers, and they don't even attempt to collect workgroups onto the same server.

Therefore, stores with an SIS of 3 mean an average of 3 references per message. I find it rare to see SISs less than 2, unless there is very little intraoffice email exchanged. ------------------------------------------------------ Roger D.
