Outlook 2003 doesn't send mails after installation of OotD

I cannot send any mails after having installed OotD.

The testmail works perfectly, however, the mail I want to send remains in the outbox.

Outlook is asking me for my password but it still doesn't work.

In the meantime I uninstalled OotD but I still have the same problem with Outlook 2003.

Any ideas?
