open two instances of outlook with seperate profiles

[ritchy71]

I have a few users who require sending email from two
different mailboxes with different senders as in: jbloggs
and ITsupport. When they compose the email, they must
enter in the 'From' name.

Is there any way to automatically set this up so that when
they send from the 2nd profile/mailbox, the recipient sees
that it came from the 'ITsupport' and same fro
the 'jbloggs mail? Or does it always default to a the
profile that was used to open Outlook?

many thanks!
