I am using Outlook 2000 and I have two mailboxes. When I send of
behalf of the mailbox A the message get stored in the sent folder for
mailbox B. Is there any what using VBA (I tried rules and it did not
work) that I can get messages sent on behalf of mailbox A to be
stored in the Sent folder for mailbox A?

You might look into UniSent at www.ivasoft.biz - nothing built into Exchange
or Outlook (outside of rules) will do this.
