OL2000 send options

[Karen]

I am using OL2000 through an Exchange Server at work. I
have been able to add my POP3 Road Runner account and
receive RR message through OL. However, I would like to
be able to send through the RR account too - how can I do
this? In OL2003, there is an option to change Accounts
when creating a new message - is there a similar feature
in OL2000?

Thanks,
Karen
