I am new to Exchange and am checking email addresses for some of our users as some people have been getting email destined for them sent to other users also. I have found that the X400 address has other users names in there for given name (g) and surname (s). I suspect this is the issue. Exactly what should the given name (g) and the surname (s) be? Should they match the first and last name of the user account? I want to get this correct, so I need to know precisely what it should be when I edit it.
