I need in same Outlook 2003 session, to Imap to another email box.

I need, via Outllok 2003, to IMAP to another mail box, and then to be able to
send as that other user account with their mail address being shown and not
the original.

Is there a way to do this?

Thanks, BobW.

PS: I have tried this and so far can send via Account button select for
other account. Bu still sends from the primary mail address. I need to fix
this part.
