You aren't supposed to be able to change it. That is why you are having so
much trouble. You will probably need to write or get someone else to write it
for you.
Does your boss realize that she won't be able to reply to these messages?

What kind of phone does she have? Can it be set to pull from an IMAP or pop3

MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
