Using outlook as a user, there are 2 ways to change the 'from' field,
one is actually choosing or typing in address in the 'from' line, but
that outputs a 'sent on behalf of' type of message. Using the
Accounts drop-down changes the low-level fields. The latter is
functionality I want.

Is it actually as easy as changing the PR_SENDER properties? Or do I
have to actually login into that account and send it from there? If
so, how can I take all my existing properties with me?

Of course, if there is a simpler way of doing this using OOM (without
security warnings), I would like to know about that too.

Thanks in advance,
