Correct. The /a and /m switched are mutually exclusive. If you look at
your Help again in the description of the /m switch it says, "Only works in
conjunction with the /c command-line switch." In other words, if you use
/m, the only other switch you can use on the same command line is /c.

Conceivably you can use a mailto shortcut to click on in a document or a
draft item. See http://www.ianr.unl.edu/internet/mailto.html
