Outlook 2003 - Conflict with mailboxes

[Manuel Jiménez]

Until now we were working with Outlook 2000. Some users have two accounts,
one with Exchange (for intranet mail) and one with MDaemon (for internet
mail).
At the configuration we have setting Outlook search first at Intranet mail
and after search at Exchange. It works and e. g. an e-mail for two recipients
(one for internet and another for intranet) the e-mail was sended to both
addresses perfectly.
But now we just updated to Outlook 2003 and we have the follow problem:
1.- Outlook send the e-mail by the default account (e.g. Exchange) even if
the recipient is a Intranet address.
2.- Before send an e-mail you can choose the account you want, but you must
take care about it.
3.- At the situation like we use of some recipients (internet and intranet
addresses) in one e-mail now we must to split the e-mail in two e-mails (one
for sending by Exchange and other for sending by MDaemon) in order that all
recipients will receive the e-mail.
Is there any way to configure Outlook 2003 in order that it works equal as
Outlook 2000?
Thanks you in advanced.
