Can't delete email from trash (in entourage)

I have a problem with 5 emails in my email trash(deleted mail).
It is not referred to the trash-can on the desktop.

Every time I try to delete them one by one or by choosing all of them, entourage freezes and has to force-close it.

Can't get it up running again fully, untill restarted computer fully.

Here is a picture of the 5 emails in question, subject and email-adresses removed.

How can I delete those?

Thanks in advance

Did you try shutting down Entourage first?

att: yes I have tried to shut down entourage first.
But that does not make sense since these 5 emails is in the trash/deleted email folder inside entourage.
