I was under the impression that in outlook and outlook express, when the mail opened it was off the mail server. I could be wrong, but depending on how your mail server is set up it should not stay on the server unless it is specifically set up that way. At home, mine goes to the hard drive when opened. At work ALL mail stays on the server because corporate wants it that way.

If your equation requires either a complex combination of variables to get the desired result OR you can't seem to get the result regardless of the variables....it ain't your variables, it's your constant.
