Disabling the 'From' option within New Message

[vex]

Is there a way to disable the 'From' option on the Options drop-down on
the new message. I was looking at this yesterday. I was able to
select a user's email address other than my own to be the sender.

Where can this be disabled? Outlook 2003/Exchange2003


Thanks in advance

You can't disable it, but unless you have Send as permissions, it will
either send as "on behalf of" (if you are a delegate) or come back as
undeliverable.
