When the user sends a message which account is used.  Check the mail account
being used in the client by adding the column E-mail Account to the Outlook
view.  It could be that by default the Exchange (MAPI) account is being used
and not the IMAP4.

Subject: [exchangelist] [Exchange/Outlook] Exchange + IMAP accounts: can't
send mails through SMTP

Hi, subject isn't explicit so I develop my problem:
I administer an Exchange 2000 server with Outlook 2003 clients. Mailing
features have to be available when working online (connected to LAN) as well
as offline (through an Internet connection).
Since RPC over HTTP isn't available in Exchange 2000, I thought the best
solution was to have an IMAP access to Exchange mailboxes.
This is the reason why each Outlook client has 2 mail accounts: Microsoft
Exchange Server and IMAP. Actually, they refer to the same mailbox, but I
created Send/Receive groups so as to synchronize Exchange account when
online and IMAP account when offline.
This works fine except the fact that email can't be sent when offline: I
noticed that Outlook was actually trying to send emails through Exchange
account, although it is disabled in offline mode.
Note that my IMAP account works fine when no exchange account is added to
the MAPI profile, so I suppose there is no problem with IMAP or SMTP
settings. In this case, each created mail is stored in personal folders
outbox, whereas it is stored in Exchange outbox when an Exchange account

Do you understand what's going wrong?
Is it that the solution I described is wrong? Is there a better way to send
and receive mails through internet?

Really thanks for help.
